Weekly SDAST Chat Meeting #79: Wednesday 1st October 2003 Participants: Silvia Martìnez-Nuñez, Niels Joergen Westergaard, Stefan Larsson, Sami Maisala, Jerome Chenevez Action Items: None **** Logging Started : Wed Oct 01 12:49:32 MEST 2003 > Hej Niels Joergen ! Are you already well installed in Peter office ? > Do you know when is he coming back from his holidays ? END Hello Silvia, yes I'm here at Peter's office. I think he'll be back the coming monday Oct 6. I just got a message from Mathias Beck and Nicolas Produit that the IC files will be re-installed. END Nicolas found a bug END > That's great ! I have just sent a message to Sami, because his executables crash wiht the latest ic_tree when I try to run with not simulated BKG. END > I will inform Sami about this bug. END > I am afraid we are not going to have a very productive Chat. Carol Anne is sick, Sami has not answered to the Chat e-mails. But Stefan told me he will be present. Then lets wait 10 minutes, if anyone connect we cancel the Chat. END Alright, sounds reasonable END *** Sami (~smaisala@gemini.astro.helsinki.fi) has joined channel #jemxadr Hello Sami, how are you? END *** larsson (~larsson@tenma.dsri.dk) has joined channel #jemxadr Hi Folks! END Hello Stefan END Carol Anne will not be with us today, she is sick. Peter is still on holiday END Hi everybody. END Jerome should be there, though, I've got an email half an hour ago END Hello Sami END > Hi everyone ! Should we start ? END * njw Yes, do you have the proposed agenda ? END > Yes, I have ! Let's follow Carol Anne agenda End * njw log *** jerome (~jerome@uhuru.dsri.dk) has joined channel #jemxadr Hello guys. I am sorry to be late... I was in dsicussion with carl and did not see the time! > then the first to the ring is Niels Joergen ! Tell us how is going with your near-future deliveries END I have updated the code for j_ima_shadowgram to include the background, but I've had some troubles testing it. I hope that being here at ISDC canspeed that up. The change of j_ima_basic_recon to produce variance and significance maps (for the mosaicing process) is therefore delayed. The update of j_ima_src_find is also done (let the catalog sources override the found sources) but not tested. That is the status. END > Could I take from the ISDC system the latest version of your j_ima_src_find to test the scripts ? From where ? END It is lacking a small change. I'll notify you when it is done - today END > Mange tak, Niels Joergen ! END > Any questions on IMA ? END > If not, Sami please tell us about the BKG status END I have updated all JMX2 ic files and j_bkg_spat sel and j_bkg_scal_calc. I still have one SPR in my j_bkg_spec_sel executable. The problem is really weird and I haven't found any solution to that yet. I have memory back pointers in my output files and even Bruce couldn't find the reason for that. I'm just trying to check the ic files in ISDC and trying to understand why there is a problem to find models in ic tree 4.53. END > Sami, do not spend time on this bug. Niels Joergen just told me that Nicolas has found a bug on ic_tree 4.53. END That is really nice information! END Nicolas Produit mentined, that he had found a bug. I'm not sure how much he knows about the bug but perhaps you should contact him ? END I'll check through the bkg files in ic_tree 4.53 and if there is something missing I'll take contact to him. END Sami, when that is fixed, do you think that the background models will produce near-realistic results ? END I really hope so... The all is based on empty field observations. The scaling is still quite complicate. (to Silvia: I have a compiled version of j_ima_src_find-1.6.0 in /home/isdc_guest/westerga/jemx/issw/j_ima_src_find but it has NOT been tested) END OK Sami, I'll test it very soon END > (to NJ: tusink tak !) END > Any more questions on BKG ? END N N n > Sorry Sami I have one, your latest version were delivered at mid-Setember, were not they ? END The latest versions are j_bkg_spat_sel-1.4.7 j_bkg_scal_calc-1.4.8 j_bkg_spec_sel-1.4.5 > Thanks Sami ! Ok, let's move to Stefan ! END j_bkg_spec_sel will be updated really soon - the only problem is back pointers.. END My delivery for OSA 3 will not include background model handling but most of the other updates on my list. I have just sent you a mail with details of some of the upfdates I have done. My main priority has been to solve the vignetting and flux problem. I am not sure yet if I have succeded but I have made a major redesign of the extraction algorithms, so there are now two options (precisionLevel=0 is my previous algorithm with some updates and precisionLevel=20 is the new algorithm which I am still evaluating). The new option creates and uses a pixel illumination map in a similar way that Niels does (I believe). Surprisingly I seem to get very similar results with the two different codes... How far offaxis was the source (GRS1915) ? END For the scripts there are rwo new parameters (cut levels for the PIF values). I'll send you those today Silvia. END > Thanks Stefan ! END Maybe differences will pop up if you go even more offaxis END GRS1915 was offaxis to give a vignetting factor of 0.65 Yes, I need to check different directions in the field of view. END Any other Q? END > Stefan, when will you deliver your new software ? Only I can instroduce the new paramters when your executables are accepted by ISDC. END What about hte lightcurve extraction ? END The same code is used by LC extraction. OK OK Silvia, that might be a problem. If we run out of time you have to ignore thoose parameters this time. They will simply not be accessable from the script. END > That's is what I am going to do. Any more question Source Extraction ? END N N N > Next is j_scripts. I will deliver a new version tomorrow (at last next Friday) with close nearly all the SPR and SCREWs, except the ones related with j_ima_src_find and the time resolved phase lc - may be, we do not need to introducce changes on the scripts. Not for the lc I think. END > And then, next week during my stay at ISDC I can discuss with Peter the phase resolved lc issue and introducce the new j_ima_src_find parameters and may be the new source extraction paramteres. Any questions ? END N n N > Then next on the agenda is Instrument Model, any news? END Not really, we are working on an update of the RMF, response matrix, but the analysis has not yet shown what the energy resolution really is. On top of the intrinsic resolution there are glitches in the gain that affect the resulting resolution. So a new release is pending - perhaps in two weeks. END > Thanks Niels Joergen ! Then next on the agend is you again, do you want to tell us something about the mosaicing tool ? END We have a primitive one that works with Niels' and Carl's images. Perhaps Jerome should tell us about the better version where variance map and vignetting is taken into account END Sorry, I was in telephone with Niels... He is coming back to DSRI in a moment. Well, in the meantime I can say that we've been looking for SGR-A with this mosaicing but never saw a hint of a source END CAO has also just called me up. She wanted to say that she only has a little SCREW to deliver before the OSA_3 freezing. About mosaicing, I can say that the work is still in progress. I have managed to make a mosaic image from 10 NJW's sky images (200X200) but right now I am beating with a bug in my pgm which does not run with Carl's images (262X262)! We will see the effect of the weighting only when I will be able to manage Carl's images, which include variance maps. Any questions? END > Sorry Jerome a silly question, is this new tool going to be delivered to ISDC or it is an offline tool ? END For the moment it is not foreseen to be delivered to ISDC. END > Next on the agenda Jerome, do you have any news about our trips to ISDC ? END The GCDE observations seem to end on Oct. 18th. After NJW it will be Silvia's turn and then Carl's to be at ISDC. CAO should take the last turn, but no hotels in the whole region of geneva are available during this period! So they work 24 hours eight. END By the way Niels Jørgen, is there any activity about GCDE at ISDC for the moment (like people shouting in the corridor they have found a fantastic new source :)? No it 's rather silent, but I've not been here for so long END Yes, that is right. Has any of you looked at these observations yet? END N (coding....) END N > N (coding ... and debugging ) END Ok. Silvia, dou you have booked your hotel? END > Yes, Franca did ! END > I hope everything will be already, because I am arriving quite late on Sunday 5th. Niels Joergen could you please do it a favour ? Great. So we will cover most of the period anyway. And then PK will be back. END > Coudl you pleas ask at Hotel des Balances if the have a booking for me from 5th to 8th Oct. (just to confirmed) ? Last time, they forgot I was comning Sunday late afternoon ! Thanks ! END Yes, certainly, I'll ask for confirmation END > Ok, I think we should try to finish our Chat and go back to work. Do you have close some AI ? END > (to NJW: mange tak) N > Do you have any wonderful new (AOB) to tell us ? END N N N N > Then, I will send the log file to Carol Anne. See you soon ! And good luck with the deliveries ! END > Hej, hej ! END By OK Silvia, that is great beacuse I was also taking the log... But I guess *** njw has left channel #jemxadr : (njw) you have the beginning, which I do not have. END Bye. END *** Signoff: larsson () > At the same time, I can ask Carol Anne how she feel ! au revoir! END
