Subject: JEM-X Monday Meeting 2007-06-18

Participants: SB, NL, CBJ, NJW.

JEM-X status (SB): Hotspot activity is very low or absent. The gain is a bit low
in revolution 570 but temperature is also low. An increase of the gain is seen
together with an increase of the temperature.
The resent ESAM* situation has not changed the JEM-X properties.
JEM-X was out data-taking for about 10 hours.

Time-relation (SB): The phase shift between the first peak seen in radio and
X-ray (here ISGRI) is around -270 micro-s. There has been found a time jump
of 48 micro-s at a ground station hand-over. Often this glitch is smaller than
this.

ISDC visit (NJW): Time was mostly devoted to the development of j_ima_cross
together with Stephane Paltani. At the end j_ima_cross could be part of
a pipeline, although there were some loose ends such as the correction for
collimator vignetting and accurate source positioning for which j_ima_src_locator
is foreseen.
