Subject: JEM-X Monday Meeting 2006-11-20
Date: Fri, 22 Dec 2006 11:07:26 +0100 (MET)

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

JEM-X status (SB): Eclipse season will finish soon. Status is nominal.
A very rapid switch-off of the DFEE has caused some start-up problems.
SB will look into it.

Report from ISDC (CBJ): IDL software was handed over to Stephane Paltani
who will be in charge for converting to ISDC compatibility.
A number of comparison cases showed that the IDL software is at least as
sensitive as the ISSW (j_ima_iros). SP will continue the work and hope
to have something running before Dec. 31, 2006.

Shadowgram distortions (NL): By comparing expected hole positions with
actual hole positions as measured in observations of a strong source
close to on-axis there are some distortions that were not present
during the ground calibration. The largest size of this distortion
is around 1 mm. The reason for this can be the lower voltage applied
now as opposed to the calibration situation in Ferrara where the
gain was three times higher.

New OSA6 (NL, NJW): The new deadline (Dec. 7, 2006) for OSA6 code freeze
opens possibilities to deliver new versions. The BPL version with
shortened collimator to increase sensitivity can be delivered before
the deadline. The user can specifiy the collimator model by the
choice of BPL version. The image correction parameters (power and
normalization) are given as FITS keywords.

Ground coordination meeting at DNSC (NL): SB and NL will participate
in this meeting; CAO will take notes most of the time.
Next Crab calibration will also be discussed this meeting.
