______________________________________________________________________ * * * OSA News 30-MAR-2012 * * * ______________________________________________________________________ Release of updated JEM-X calibration ==================================== Some of you might have noticed that using the JEM-X Instrument Model (IMOD) files (v.21), there was a spurious instrumental feature at ~7 keV. The instrument team worked hard on this issue and they produced an updated set of IMOD files to better correct the time evolution of the JEM-X detectors and avoid instrumental features.This new version of these IMOD files (v. 22) is now available in the Instrument Characteristics (IC) tree and constitutes a significant improvement on the previous versions, so we recommend that users download an updated version of the IC files following the instructions of the ISDC download page. This is a good practice before starting any new INTEGRAL analysis as the IC tree is regularly updated with contributions from the instrument teams. ______________________________________________________________________ |
