JEM-X MONDAY MEETING #62: 27/6/2005
	
SUMMARY
	Instrument status: Could do to order a drop in HV for JEM-X for end of
		July. SB to estimate when it should be.
	Co-ordination meeting: NL attended and two JEM-X specific points raised.
		Firstly, we want to be protected from Scorpius overload, but
		limit should be increased to avoid too many shutdowns. This
		needs good communication between MOC and ISOC, even for
		scheduled observations and almost impossible for TOOs.
		Secondly, switch-on procedure will be changed to remove the
		initial low switch-on since we no longer see significant gain
		decays at beginning of revolutions, only after unscheduled
		switch-offs.
	SVR and OSA5.0: NJW to finish SVR before going on holiday. NL wants to
		re-deliver j_ima_iros. ISDC is still waiting for ISGR matrices.
		JC has redelivered j_ima_mosaic. NL will write ISDC newsletter
		article about OSA 5.0 changes for JEM-X. Still some problems
		with position offsets produced by j_ima_iros because certain
		parameters set wrong. 
	GRB 050626: Another GRB, but not in core program. This one belongs to
		the Russians. However, people tend to overlook JEM-X when 
		making burst proposals, and are perhaps unaware that it can
		see GRBs. NL noticed that IBAS position determination
		consistently to JEM-X determinations.
	Crab calibrations: NL has looked at rev 39 where flux has an apparent
		decay. CBJ will also look at rev. 39 again. Is gain stable?
		Could the problem be with deadtime calculation, hot pixels,
		background, rejection criteria? At low energies see a decay
		in flux with time, and at high energies see and increase in
		flux, so could be a change in gain coupled with strict
		rejection criteria.
