JEM-X Monday Meeting 19/11/2007

Present: SB, CAO, JC, NL, NJW, CBJ

1) Status of JEM-X instruments
	SB  has nothing to report. Gain is very high and temperature has been 
	climbing up to 27 degrees the last few days.
	HV will be stepped down in the next orbit 623. 
	Must ensure that the operational dB is updated ASAP. 
	TOO starting in the next orbit for a couple of orbits.


2) SB: Report from IUG meeting last week
	Integral User Group meeting in ESTEC last Thursday and Friday.  
	No longer ISWT, first meeting with the new format/membership. 
	Wim Hermensen is new chairman. 
	Mission status: extended till end of 2012, including rolling extensions 	
	(first in 2 years). 
	ISGRI calibration is improving (spectral snakes problem caused by
	risetimes). Cross-calibration between SPI and IBIS much better now.	
	Discussion about using more observing time on calibration.
	Time calibration was also discussed. Wim and colleagues have looked at
	this problem. Changes seemed to have helped stability of Crab pulsar. 

	Core Program will end at the end of next year.
	Russians still get their 23% share of data, also after the end of 2008.
	What is our strategy for a galactic (i.e. nearby) supernova?
	Discussion about our Workshop next year. (see below)


3) OSA Status
	NJW: has worked on this the last week while NL waits for IMOD updates. 
	NJW updated the archive at DNSC.
	JC has questions about using og_clean at start of this processing to 
	ensure that the new corrected data is used instead of the archived
	values.
	CBJ: very positive that his results and those from JC's mosaics agreed 
	very well. 
	NJW: now that we have lots more data and experience we should make
	ARF that fits the actual gain of the instrument.
	We have a tool that can be used as a forestep for NL's image, in 
	conjunction with the new IMOD tables with new information
	needed for better imaging (.e.g. alignment parameters, parallax 
	offset), some of which has come from CBJ. 
	SPAG table is now read in by imag_iros to account for differences in 
	electronic efficiency and effective pixel size. 
	CBJ has made a collimator model from first principles, that doesn't 
	include the interplay with the mask.

4) SDAST meeting next week
	Starting Wednesday morning to accomodate ISDC/ESOC  people.
	Possibly must have supper together on Tuesday evening. 
	we have an OSA version 7.05 of JEM-X software. 
	NJW still to make the agenda. Will circulate it tomorrow. 
	Stephane should give a clear description of what he wants for image
	output for the next official OSA release. 
	Should also discuss the joint-analysis cookbook about how to merge JEM-X
	and SPI data, for naive users.
	

5) Crab Calibration
	We should look into cross calibration with other instruments. 
	NJW still working on last Crab calibration.
	We should keep an eye on the cross-calibration forum whose last meeting
	was in California, and next year's meeting will be in Germany.  

6) Copenhagen 2008 workshop
	SB: Proceedings will cost a great deal to print. PoS (Proceedings of
	 Science): Based in Trieste, International School for Advanced Studies. 	
	 A web-based solution where all can click in and see the papers.
	 What about copyright? Creative Commons License is one solution (CC).
	 We're now looking at a registration fee of 200 euros, which is  quite
	 low, but without dinner. Should students pay only 100 euros? 

7) AOB - none
