JEM-X MONDAY MEETING #57: 17/5/2005
	
SUMMARY
	Instrument Status: Everything running okay. IREM crashed in rev. 314
		but JEM-X no longer dependant on it. GRS 1915 caused an
		automatic switch off due to high count rate. Varying radiation
		belt countrates suggest solar wind is extending radiaiton
		belts upward/outward at the moment.
	GRS 1915: QPOs (Quasi-Periodic Oscillations) observed with patterns
		that last for a while and then are replaced by another pattern.
	GRBs : GRB 050502 also seen by SWIFT and positions agree with JEM-X to
		within half arcmin. Weaker of the two GRBs, 050504 also seen
		by SWIFT and XRT with positions within 1 pixel of JEM-X's.
		These were short bursts of about 30 msec.
	OSA status: Crash on j_ima_iros being debugged by Jake at ISDC. 
		j_ima_iros 1.3.1 just delivered. No ISDC testing of JC's
		mosaicking component yet, so no bugs found. CAO still working
		on Xe gain aging factors. RW still opposed to delivery of
		j_cor_gain that produces dynamic detector maps.
	Crab calibrations: NL working on shadowgrams of 19 SCWs from the fine
		dithering. Can clearly see collimator modulation using folding.
		Amplifier positions also produce periodic position disturbances.
		PSF of event position clearly depends on whether event is
		detected by one amplifier, equally by two amplifiers or
		partially by two amplifiers. Leads to periodic variations in
		position and energy resolution. Collimator modulation
		produces flux modulation between 40 cts and 65 cts.
		NJW not completed instrumental calibrations using SL's spectral
		extraction. Most results agree with  previous analyses
		except for last two calibrations where we get more flux
		through at lower energies due to less restrictive rejection
		criteria.
	Nyborg Meeting: SB, NL and JC all signed up.
