JEM-X MONDAY MEETING #58: 23/05/2005
	
SUMMARY
	Instrument status: We've had two GRBs, one on Friday which we could see,
		and one on Sunday which we couldn't. Now in eclipse season,
		so cold start after perigee. Temp. starts at about 0 deg. and
		takes about half a day to warm up to 22-23 deg., and nearly a
		day for entire detector to stabilise. Unexpected switch off
		at beginning of rev. 317, hence OEMs we've received. Satellite
		is in good shape, lots of fuel left. Most fuel used to recover
		from the ESAM that occurred.
	OSA5.0: j_ima_iros redelivered. Fluxes still need better error
		estimates. Crab lightcurve sent by Stephane discussed: should 
		be flat but is actually all over the place. Vignetting 
		correction could be one problem, so could spurious sources
		identified as Crab.
	GRBs: GRB-050520 seen by JEM-X, IBIS and SWIFT. Clear pre-burst peak
		that's strongest in higher JEM-X bands. We should publicise
		the fact that we've seen this GRB or everyone will assume we
		haven't. We probably see so many GRBs at moment because we're
		not looking into the galactic plane.
		
	Crab calibration: NL still looking at 19 SCWs from micro-dithering to
		study effect of collimator and amplifier positions. Carl doing
		similar studies on ipf data. NL can see periodic position
		errors due to amplifier positions. Need to model electron
		cloud motion/spread to do full position corrections
		
	ISWT meeting 15-16 June. SB to go to co-ordination meeting.
