Subject: JEM-X Monday Meeting 2008-01-07
Date: Wed, 23 Jan 2008 13:11:30 +0100 (MET)

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

JEM-X status (SB): Has been running peacefully during Christmas and New Year.
Data connection between MOC and ISDC was lost for some hours.
A very short duration (~30s) hot spot appeared.
5 anodes have been lost in 2007 (6 in 2006). Gain has been relatively low partly due
to rather low temperatures but also due to a recent HV reduction.

Calibration (NJW): DETE-IMOD determination to be changed to DETN-MOD with a new range
of STATUS values to be made consistent with STATUS in the event list.
We will define new epochs of duration about half a year for IMOD.

Use of FLAG (JC): We can use the column 'JEMX_FLAG' as we wish.

j_ima_iros (NL): There is a development of the Crab flux with time which is also
seen with j_src_lc implying that there are conditions 'outside the software' that
change. It could be the anode development - to be investigated.
Has the correction for the electronic efficiency been correctly done?

Next SDAST meeting (NJW): We aim for mid-February meeting, but NL may be absent.
Will check.
