Subject: JEM-X Monday Meeting 2007-09-24
Date: Mon, 24 Sep 2007 14:04:23 +0200 (MEST)

Participants: SB, JC, NL, NJW.

JEM-X status (SB): High Anode Rejection: A limit on the countrate of events that give signal
higher than PHA=~1000 (approx. 40 keV). The current rate limit is 9000 per 8 s, but as
the solar minimum gets deeper, the charged particle background count rate increases. The
particles give high signal so the limit is passed several times implying a GTI
elimination of a time interval that in all other aspects gives good data.

The files that define these settings for the have been updated by JC to a value of 15000 (per 8s)
in stead of 9000.

Else no comments on the status.

Crab calibration (SB): Our telemetry allocation will be 15 packets per instrument
in our 10 ks staring. In the remainder we have 2 packets for JMX2, 6 for JMX1.
This will be revolution 605 starting Thursday.

OSA status and testing (NJW): j_ima_iros has been delivered several times due to
missing initializations and NaN problems and the version is now 2.1.4.

Coordination and IUG meetings (SB): Uncertain when the coordination meeting will happen and
the IUG meeting will be in the beginning of November (2007).
