Subject: JEM-X Monday Meeting 2006-05-29

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

JEM-X status (SB): JMX2 DPE has been switched off in beginning of revolution 
441.
Gain correction works smoothly.

Sco X-1 and other high count rate data (JC): New JMXi-GOOD-LIM IC file has
been updated with the tool of Reiner Rolf and delivered 2006-05-23.

Web based HK overview (SB): The presention has been improved. An example of
revolution 436 where the relaxation takes 12 hours together with a temperature
increase (we are moving out of the eclipse season). The effect of the ion-drift
in the glass (which is visible when out of the eclipse season) is not visible.
The gain is a quite strong function of the temperature and the temperature
sensor does not precisely follow the temperature of the glass plate.

OSA6 status (CAO): j_calib_gain_fitting is now ready for delivery, perhaps 
tomorrow.
Strong greyfiltering condition seems to lead to increased noise contamination in
one of the calibration sources (#4 on JMX1, the weakest one).

OSA6 status (NL, NJW): j_src_properties. j_pif2events subroutine has been made
but PIF values are not correct yet - could be a normalization error. A PIF-map
is generated for each of the 256 PI energy values. First a geometrical PIF is
constructed, then the energy dependence and penetration into gas effects are
added. This is given for each source position. There is a weight factor assigned
to each pixel depending on the contributions from other sources besides the
background.

ATEL #817 with refined position of IGR J08408-4503 has been issued. An improved
position from SWIFT has further narrowed the position to about 5 arcsec.
