New calibration products releases since last CUC meeting. Chandra Calibration Status HETG ACIS Gain correction files for epochs 33 and 34 were released in CALDB 3.4.5 (June 2008) and 3.5.0 (Sep. 2008). 1. An order separation file (OSIP) for an ACIS operating temperature of T=-110 C was released in CALDB 3.5.0.

Continue testing HRMA effective area models with in-flight imaging and gratings data. • Adjust the HETG gratings transmission efficiency and the HRC-S QE accordingly. • Validate the in-flight HRMA effective area model with gratings and cluster data. Things to do
