Subject: JEM-X Monday Meeting 2007-11-05
Date: Mon,  5 Nov 2007 13:54:35 +0100 (MET)

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

Status for JEM-X (SB): Recovery of CRC anomaly following eclipse was performed.
Else nothing to report.

Upper threshold was struck in the QL processing because the software used
is an outdated version.*

The temperature influence on the gain has risen from 1% per degree in 2004
to about 3% now. In the eclipse season the temperature variations in an
orbit can be more than 7 degrees. Therefore the gain variations cannot be
kept within +-10% as is the goal for the HV reductions.
The temperature variations can be restrained to lower amplitudes if power
is maintained on the instruments all the time.

ISSW (NL): New developments in j_ima_iros where an intermediate delivery
is considered.

AOB (JC): The timeStart/timeStop values in the GUI has 6 digit accuracy
after the decimal point, but the saving and restoring of a GUI session
leaves only 2 digits. This has not been properly documented and we must
take steps to do that.

Dear Niels Joergen,

A small correction:

It was an old IC file (i.e., IC 7.0!), not software.

We have updated the master table, and now we use the new LIM
file for the operations (i.e., we sort of created an internal
IC release 7.0.1).

Best regards,
Stéphane
