SDAST Chat Meeting #108: Wednesday 14th September 2005 Participants: Peter Kretschmar, Silvia Martinez-Nunez, Jerome Chenevez, Niels Joergen Westergaard, Carol Anne Oxborrow Subjects discussed: 1) Raised SPRs and SCREWs and status for OSA 5.1 - CAO to investigate which SPRs/SCREWs are really not closed and send to do lists to each SDAST member - All open SPRs will be closed by end of September for j_ima_shadowgram, scrips and j_ima_iros (if the latter is re-delivered) - SPR on delivered gain history tables will first be discussed at SDAST meeting 3) Agenda items for SDAST meeting and other arrangements for meeting. - NJW to circulate detailed draft agenda - Tim and Peter to discuss future participation on Thursday morning - No spectral extraction experts lined up for meeting so far - Future spectal extraction will mostly have to deal with collimator and instrument details, not background subtraction 4) Science results for Consortium meeting - PK, SMN and CAO will definitely not be going to the meeting - JC should have results on GX3+1 (JC first author!) - SMN will contribute results on BQCam. - PK will contribute Vela X-1 results 5) AI list - everyone to distribute their status before the SDAST meeting 6) AOB - none Action Items AI050914_1 NJW 2005/09/16 Circulate a detailed agenda for the SDAST meeting OPEN AI050914_2 ALL 2005/09/16 Send CAO an email detailing AI activity and status OPEN **** Logging Started : Wed Sep 14 11:01:11 MEST 2005 *** silvia (~silvia@130.226.216.2) has joined channel #jemxadr > Hello Peter! How are you?? END > Hello Silvia, thanks for your emails. END Good morning ! END *** jerome (~jerome@130.226.216.3) has joined channel #jemxadr Carol Anne, you are welcome END Hello Peter and Carol Anne and Silvia END Hello everyone! END Hi there, nice to 'see' you all! END > Jerome, you left your biscuits here. shall I deal with them? END > I think this is the full complement of people today - Stafan can't make it Yes, if pay for the post! :) END > so shall we begin? ENd Y > First on the agenda is raised SPRs and SCREWs - I hope you all tried the > link that Stephane sent last week. The list that link generates seems to > be populated with some very old items that I sincerely hope were closed > ages ago. Has anyone apart from Silvia looked into their open items to see > if they really are open? Could you each please give a status of your > known open SPRs and SCREWs? END I replied to Silvia's mail yesterday evening still. END As i told you, I did have a look at theme, and got the feelin that most of them where obsolete. END > Thanks Peter, I saw that one. END > I'm planning to go through the delivery notes and find out whether packages > have been delivered against the items on Stephane's list. What about Those on the scripts that are open are usually not doing any harm but as a cleanup one could as well fix them. END > you NJW? END I plan to close all the open SPRs/SCREWs this week. END > That's great work Silvia. END There are some on j_ima_shadowgram that are not closed and not obsolete. > But they'll be closed by the end of September, right? END I'll try to deal with the most important ones. It remains to be seen if j_ima_iros will be redelivered for OSA5.1 - if so we can get rid of the SPRs END > If j_ima_iros is redelivered, you're going to be VERY busy. END > While my refined aging factor data runs I'll take a look at every component > and see what's really still open, so you can expect a to do list from > me in the next couple of days. Any more comments on this point? Just one question about SCREW 1758 -- Corrected gain fitting tables, do I have to modify the scripts to handle this issue ? I'm not sure about our final conclusion in this point. END > This SCREW has not been approved by ISDC yet, and I've not talked to > Stephane about it, which would seem to be a necessary preliminary step. > I think ISDC just wants to handle the SPRs and things that don't require Before the idea of OSA 5.1 end of the month came up, I thought we could discuss it calmly in Copenhagen. > major changes and have already been accepted, so I don't see this one * oxborrow begin done for > O"SA 5.1 END Ok. I'll keep this one in mind for a future delivery. Just keep me inform about the discussion in the meeting. END It seems to me that as minimu service it would be suifficient to have both kinds of tables and tell the user in documentation to manually select the non-standard one for certain revolutions. But whatever, we should not make this jkind of change in the scripts in a hurry. END > We'll discuss the exact f > implementation at the SDAST meeting. END Perfect END > Any other questions concerning OSA 5.1? N N N N > Okay then, on to agenda items for the SDAST meeting. Any one got anything > to add? END Could we get a (pre)final version of this agenda? END Si the discussion how Tim and I help the JEM-X team in the coming months part of the normal meeting or will we do this separately Thursday morning? END I'm not sure when Tim will arrive but it would be to make good use of the morning to that discussion then END It can be discussed in the general meeting, but hopefully in a short time END My understanding is that he would also be available Thursday morning. Should I ask him again or do you want to contact him directly? END I'll ask him END > Are we having a separate session on spectral extraction, have known > experts been invited? END I have heard nothing from Niels on invited experts, so I beleve that for the time being we will have start in the SDAST (with Stéphane etc.) END > Does anyone know if Stefan every implemented the background subtraction > based on Sami's background models? It seemed like he was always on the > verge of doing this. I don't think we can throw all Stefan's work overboard > before we can be sure that things aren't improved significantly by using > the background subtraction technique we've been planning for so long. END It is my firm impression that he never really got there. Stefan just does his own background correction and does not use Sami's models. END > So all Sami's work will also be wasted? END From a modeling point of view, it seems yes. It went into a dead alley, which is not Sami's fault. His efforts have brought us some interesting insights in the real background though. END > I don't think it is a dead alley if it never got implemented - we just don't > know if it could help or not. END In fact the various problems with imaging and source extraction are mostly related to the intricacies of the detector response and interaction with the collimator mor than they have to do with the background. I think that that is the reason why Sami's work never got into play END It will be easier to explain that in person than via a keyboard, but it turns also out that usually you want to avoid zones of high background while the rest is rather easy to handle instead of trying to model it which leads ... to its own systematic effects. END > I've been modelling the Xe, Mo and Cu lines at 29.6, 17.4 and 8.04 keV, and > it seems to me, that some of the funny bumps people have spotted at low > energies could well be the Cu line from the collimator, which would appear > over the entire detector, and could presumably easily be spotted by a model > that was aware of the Cu line position (e.g. a model like Sami's). Just my > 2 cents. Any more comments on the SDAST meeting? END No, except that it is probably time to make a more detailed agenda now END Agreed Tim will arrive wednesday night so he'll be available Thursday morning END > That's an AI on you NJW to circulate a detailed agenda by tomorrow. END Just one. Since I'll not attend to the meeting, next week I'll send you an e-mail with the scripts status and inputs for the others points I'm involved. END > Thanks. We'll still miss you though. END > Next point on the agenda: science results and/or the ISDC Consortium > Meeting. Who's going to the meeting, and do we have anything interesting > to show for it? END I'm _not_ coming unfortunately, even though I will be at ISDC on Wednesday morning to give the "Integral" talk. > Personally, I can't attend because my husband's at a workshop in Lund all > that week. END Lars will be absent that week and wants me to be here as much as possible. END I'll go to the consortium meeting, but unfortunately I have no science results END I will not go to consortium meeting. END May be, I can give you science results to show in the meeting. If I manage to finish something this week, I'll send you a detail e-mail and a nearly ready paper on BQCam. END I'd appreciate that very much, Silvia. Perhaps Jérôme will have some too ?? END When is going to be the consortium ? END October 10/11 END Ok, then I have some extra dys to work on BQCam. END dys = days. Sorry END And I should be able to send you some Vela X-1 results. A0535+26 is rather ISGRI/SPI science. END Thanks END > Any more comments on the consortium meeting? It's nice to see we have some > actual science coming out of all this work. END N N Sorry! I was off a moment having a telephon call from Paris with very good news. END > I could give you a new gain-aging figure to show at the meeting NJW. END Now you made us curious, Jérôme END > Tell them the good news! END Thanks, Carol Anne. In fact I expect a good deal of input from the SDAST meeting well, it has just been decided that I shoulg keep the 1st place on the GX3+1 paper coming just before the consortium meeting.END I was writting at the same time as Maurizio Falanga, whitout knowing that1 1 END > Congratulations! END Thank you! Congratulations Jerome! END Very good! END Now the work is going on for the best of science. END > Sorry to barge in with boring things like AI lists again. I know you > probably haven't done any AI's but can you all please send me an email > telling me the status of EVERY one of your AIs or AI on which you are > partially responsible? Lots are probably obsolete and OBE, I'd like to > clear off all the deadwood before the meeting so we only get to discuss > important, current things. END OK, I'll try. Allright END > As Yoda would say: don't try. Do. END Yes, Mistress Yodessa! END > I have one open AI to re-arrange the SDAST forum to make it easier to > find what you need. This will be done after I've finished these gain > aging factors. The forum will also be extended to include gain histories > etc. of each revolution. This last part will take some time to complete(!) > END > Any more comments on AIs? END N N N N > Okay, do we have any other business - any thing you want to get off your > chests? END N N N N Have a nice week and a good meeting next week. Chat with all you again sometime in October. I'll be back from Rome in 21st of October. Bye-bye. END Have fun in Rome! Have a nice trip, Silvia, see you soon the rest and have a nice time, bye END See the rest of you soon in the Cold North. END Good bye Silvia, and see you others here in raining Copenhagen. > See you next week everyone - we'll be thinking of you in sunny Rome *** njw has left channel #jemxadr : (njw) END > Silvia - it's cold and rainy here. END Here, it's hot and sunny. But we really need the rain END Take care Carol Anen and I hope we will see before the end of this year. END Bye *** Signoff: peter (ircII/tkirc) hej, hej ... *** silvia has left channel #jemxadr : (silvia) > Have a good trip! you're welcome at the new spacious flat. END
