Subject: JEM-X Monday Meeting 2008-01-28 Date: Mon, 28 Jan 2008 14:25:42 +0100 (MET) Participants: SB, NL, JC, CAO, NJW. JEM-X status (SB): Nothing to report. INTEGRAL Crab intercalibration (SB, NJW): There has been a suggestion from SPI to include data from revolution 605. Since this requires the generation of a new ARF we will stick to revolution 300. OSA status, mosaic and EXPOSURE map (NL, JC): There is a bug in j_ima_iros so that the EXPOSURE map contains the number of mm2 on the detector in stead of a time unit. The implementation of the correction for electronic efficiency requires a somewhat redefined 'illumination' map. This is under revision, including e.g. a new keyword with on-axis detector area. Computing at DTU (SB, NJW): There are new possibilities including the use of 'Mathematica'. /NJW
