Subject: JEM-X Monday Meeting 2007-10-01
Date: Mon,  1 Oct 2007 14:12:44 +0200 (MEST)

Participants: SB, JC, CBJ, CAO, NJW.

JEM-X status (SB, JC): No loss of anodes. Gain is getting high for JMX1; on the
other hand the temperature is higher because two instruments have been operative
in the latest revolution 605 (just finished). We must consider a HV reduction
soon.

Crab calibration (SB): The NRT data reception server at ISDC crashed in the
beginning of revolution 605, but it was soon brought up again.

The most recent PHA binning table was not loaded to begin with for JMX2 until
after the first 24 science windows. These must be analyzed with the old
table and we prefer to flag them as BTI. There is a strong greyfiltering in
that period anyway since there is only a single packet available for science
data transmission.

The deadtime correction for strong grey filtering appears to require an update.
It will be investigated.

CAO will make an IC file with gain calibration table for this revolution.

OSA status and testing (NJW): j_ima_iros was updated in the last minute and
redelivered. OSA7 has now been released.
We must consider a SDAST meeting quite soon to define new goals for OSA7.1 and
OSA8.
j_ima_cross development will be continued with higher priority now that j_ima_iros
is out.
