SDAST Chat meeting # 109: Wednesday 11th 2005 Participants: Peter Kretschmar, Jerome Chenevez, Silvia Matinez-Nunez, Niels-Joergen Westergaard Subjects discussed: Release of OSA 5.1 or OSA 6.0 (this week!) News from ISDC: some problems with the instrument station Pyotr used new software (5.1) and some Crab problems have disappeared - see Pyotr's emails We should update known issues for OSA 5.1 We also need to provide a release note with changes from 5.0 to 5.1 Problems with crowded field spectra and number of found sources: Jerome and Silvia to look into this with Simona's help How used Simona and Tim to help track down problems Action items: send emails to CAO New gain calibration webpage, generally considered useful Updating ADD should be JC's next task Updating SVR needs to be done, but manpower still an issue - should use Tim and Andrii more for this Manpower should be discussed at next Monday meeting An extra packet for JEM-X Earth Occultation? ISOC still to decide. Next SDAST meeting: 24/25 and 28/29 not good for Peter 28/29 not good for Stefan Dates need to be found SOON (by email) How does analysis GUI `reset' button work? Determined by isdcroot All agreed it should return user to ISDC-specified parameters **** Logging Started : Wed Nov 09 11:00:23 MET 2005 > Hej Jérôme, hvordan gaar det paa ISDC ? Det gaar roligt bortset fra der var problemet med Instrument station siden i gaar, som jeg foerst hoerte om i dag. Nu er den i orden igen. Jeg har ahft et moede med Simona, som jeg fortalt dig om i mi email i gaar. *** peter (~pkretsch@isdcsf5.unige.ch) has joined channel #jemxadr > Det var godt du fik det ordnet, mangler der data ? END > Hello Peter, how are you ? END Der er et par ting vi skal snakke om sammen. END ¡Hola amigos! ¿Que tal? De manglede data skulle komme igen fra en anden maskine. END Hello Spain! Thank you Peter for your help. As you can see, it works fine. END *** silvia (~silvia@130.226.216.2) has joined channel #jemxadr Mostly fine, my back is still giving me problems frequently, but I'm now having more fundamental checks being done. END Good morning everyone Hi Silvia! > Hello Silvia > I hope that such checks will reveal some cure, Peter; do you remember to > take the time to do something else than sit on a chair and work ? END > Well, it seems that those are present that will be preset at all, so let's Occasionally ... END > begin with Carol Anne's agenda: OSA 5.1, what is the status ? Jérôme > any news form ISDC ? END > form = from END As far as I have understood what was said at the scientific meeting here last monday, OSA 5.1 should be released THIS week. Though, there were still some small problems with ISGRI ARFs and some unagreement about SPI, but that should be fixed\ for the next release... Everything from JEM-X is included. END > I've yesterday got a mail from Piotr telling that with CAO's latest deliveries > and new IMOD/RMF some of the Crab spectral problems have disappeared Very good! > (revol 0039 and 0102). END > Is there talk about another OSA5.? release, Jérôme, or will the next one be > OSA6 ? END It did not sound decided yet. But everyone speaking about the next release was refering to an OSA 6 rather than OAS 5.x . OSA END > I've got a mail from Stéphane with an urge to update the known issues for > OSA5.1. One of the items should be the crowded field spectra, do you have > some other input for this ? END Yes, he told me about that.. There was something about the nb of sources with FLAG = 1 which is different from the maximum nb of sources. He said he told you. END > Yes, that was in his mail END He told also something about a Release Note. END *** Signoff: silvia (EOF From client) > Yes, we should also produce a release note with improvements from 5.0 to 5.1 > I'll produce one and circulate it for additions/corrections END OK. As you know there is a little improvement regarding j_ima_mosaic user's interface. END * njw Sort of, could you provide me with a description ? END We also must mention that currently a weak source can be 'contaminated' by contributions from nearby bright sources - one sees this definitely in light curves. *** silvia (~silvia@130.226.216.2) has joined channel #jemxadr I will write it in your note, OK? END This is especially true, if one forces a weak source 'detection'. This would be a good topic for Simona to study ... END Sorry guys ! I've had some technical problem, the light has been cut down twice END Yes Peter. Speaking about that, I met her yesterday an we agreed about systematic testings > Hope you'll stay enlightened, Silvia, do you have some additions to the > known issues list apart from the crowded field one ? END No at the moment ! END * njw Anything else for OSA5.1 ? END of a number (~100) ScWs from the GC region. We sould discuss all who will look at which product (LC, SPectra, etc.) otherwise it may be to big work for one person. END I can help in this issue! END > It is a good idea to work through a well defined data set. We should set > a priority list - probably following the levels of the pipeline: IMA,IMA2,SPE,LCR - I could help as well, but assume about 5% of my time at the moment - sorry (in bursts, so I could once spend a day). END As I told to Simona, it may be necessary to have more than only 1 data set. > and let Jéròme and Simona pick the ScWs, do the initial IMA,IMA2 analysis 1) because to two JEM-X do not work during the same periods. > and then hand over to Silvia; would that be feasible ? END 2) Depending on the sources variations (she center her data set on GX5-1) it may be better to restrain the data on one (or two) revolution(s), but if one want to see the effect of gain correction and so on, so it is better to spread the data set on a longer period > I agree to this spreading in the light of the discussion of the gain effects. of time. Then the intrinsic sources variations may be a problem, so it would be pbetter to select other sources... * njw It would be good to compare high and low gain situation results. END All depend what wants to test and look at, I guess, END Probably we will need different data sets depending on what we want to check. As I said... END > OK, Jérôme, will you initiate this ? Silvia, do you agree to follow up with > SPE and LCR work ? END I agree. END It is initiated. I told this all to Simona yesterday afternoon. END Please keep me in the loop - while my time to _do_ something is very limited, I might have some ideas if triggered. END > It will be good to define a 'core' data set and then see what questions arise > from that. It should be possible to make additions to the data set. END I can tell that Simon's criteria is to take 100 ScWs with GX5-1 inside 3 degrees I told her to look at newer ScWs where no REST format may disturb the data set, I guess after ev. 200 should be OK, but that is only for JEM-X1. END Sorry: Simon -> Simona! END > Let's continue the discussion in emails etc. Is Simona interested in being > on the SDAST and Monday Meeting mailing lists ? END I'll ask her. The good thing is she speaks french so everything is so easier. :) END > Alright, next on the agenda: ACTION items! I'll simply ask you to do something > about them, check your actions out, mail to Carol Anne with a new date or > cancellation or ..., OK ? END OK > Status for gain calibration: Have you tested the new webpage by CAO ? > With j_calib_gain_fitting-7.2 and j_cor_gain-6.4 the gain corrections are > handled well in most cases. The fixing of the gain history tables is being > discussed by Stéphane and Mathias right now (if they are not too busy with > the OSA release). Else you've read the MMM: Monday Meeting Minutes. END > Comments ? END I have to meet with Stephane and Mathias about Gain history. END Yes, I've taken a look to it and I've even forwarded CAO's email to my IBIS contacts. I find it very useful. END > Good, Jérôme, then you can tell us about their reaction END > Silvia, Carol Anne will be pleased to hear that END > Status for imaging: I have no real comments since there is no new development * njw do you have something to say ? END N n Just the new delivery of j_ima_mosaic, but nothing big there. END > Same statement and question for source extraction; except that the promised > work on a new event extraction tool is not going anywhere at the moment > since Niels L. is the key person here and he has had many other things to do. END > Documentation: I'm not sure about the ADD except the usual urge to bring it Yes, I mentioned the source extraction issue here last monday. This is not a good new. END > up to date by the ISSW developers. But for the SVR we really need to make > some evalutaions of the ISSW capabilities. One important contribution People are concerned about gain variations propagating to Light curves and spectra... END > could be the Simona et al. systematic studies. ADD: It should normally be my next task. END > Comments on the SVR ? END > I have a comment myself: We are not exploiting well enough Tim and Andrii. Just one, njw could you pleae circulate the last version of the SVR between SDAST ? END > We have to define suited tasks for them (Tim has come up with the > CasA analysis where spectral lines are actually seen) END Should I contact Andrii about SVR? END I agree, w.r.t. them (and possibly me) not being used well enough. The problem is that we > Yes, Silvia, I will. And to Jérôme: You could ask him if he still has time need someone really coordinating this in a strong manner and feel that - again - too much is currently on NJW's shoulders. > to invest here END But I'm not really able to pick up the load either (just learned that I have to redo 4 revolutions, beacuse of a mistake in the planning files from MOC :-( ) END Ok. END I'm afraid I cannot pick up the SVR, too many things alredy to be done. Sorry > I'll bring this up on Monday for a discussion of how to do the planning END > Comment and/or AOB ? END AOB: Earth Observation Just one question, when is going to be the next SDAST meeting ? Could be on 24th nd 25th of Nov. ? END I heard by rumour, that Niels asked MOC if JEM-X could have a packet more. The whole questions is becoming complicated and we should handle this like other calibration observations, i.e. coordianted by ISOC (yours truly). END We plan a GS Coordination Meeting in Dec, where this should be finalized. END Regarding SDAST Meeting - Nov 24/25 do not work well for me (appointments and flying to Germany on Nov 25). > Niels L is here now to respond to some of this END I thought the dates was already fixed...? END Nov 28/29 I'm in Tuebingen for a seminar and discussions about science. END Was it really? END Then I missed that. END Stefan has send an e-mai ltoday he can not attend on 28th and 29th END > There is no requirement for more that the standard number of packets for the > Earth Occultation Observation END > We must have an email discussion of the SDAST meeting dates END I'll appreciate if we can take a decission about SDAST meeting this week, since I've also to plan a trip to Rome. END > Alright, let's try to reach a decision very soon END Friday, I'm in ESTEC and not sure to read my mails regularly ... END Thanks.. END > OK, I'll send out some proposed dates and let you react to those END Perfect. END OK > Is that all for now ? END Y Y > Well, good bye then and stay tuned for a couple of emails, END hej, hej ... chat with all of you in a couple of weeks, I suppose END Just a little thing: Mark Gaber told me about the new functionnality in the GUI to save and load parameters. There is also a RESET button. He was not sure how this last one should be use. Reset to default parameters in ISDC_ENV/pfiles or to the users/pfiles? END No clue, you would have to ask the ISDC S/W team for that, as this is a functionality of isdcroot. END No idea about his RESET function, I suppose this function can be controlled somehow by the scripts. I'll need to ask Reiner. END > OK, thanks Jérôme. END Yes, but it is more a "philosophical" issue, or a quastion of test if you prefer. END "question of taste" No - clearly it should be ISDC_ENV/pfiles as a user could have anything wild locally and local END pfiles must sometimes be cleaned out anyway. END Thanks, for I said it too, but Mark was not really convinced. END > Yes, Peter, that makes sense. END Actually he would let the user the flexibility to use something esle than the ISDC_ENV. So by default it will be Then, just a silly question, is this new functionality alreay implemented and work with our scripts ? END ISDC_ENV, but it could be another fixed place, and I think it becomes too complicated because it gives 2 levels of resets... END Frankly, this would be a _bad_ idea. If you want your own defaults, save & restore them. Yes Silvia. OAS 5.1 is runnning here. END Thanks again Peter. It was my point. END Discrepancies between user pfiles and current defaults are already a problem. "Reset" must go to something else. This is not an ISDC problem but an issue for every software using the 'IRAF' style parameter files. Joern Wilms used to _erase_ all user pfile directories on each new FTOOLS installation in Tuebingen after having spent several times days in hunting down a bug which turned out to be some strange pfile setting in the user's dir. END Do you think the lambda user (not espcially experienced with OSA) is aware about PFILES? END He once recommended that the ISDC installation script should do the same. END It's a matter of teaching and actually not enough - another reason for Reset=distribution default. END Agree. END OK, anything else? > Can we officially close this session now ? END N YES END YES END hei hej ... > N Y *** silvia has left channel #jemxadr : (silvia) Bye! *** Signoff: peter (ircII/tkirc) Au revoir. END > Bye
