Cycle 19 PIMMS Effective Areas
Released as of 13 DEC 2016
The PIMMS Cycle 19 effective areas are illustrated below. As is always the case, the time-delay factor for the ACIS contaminant build-up has been updated. For Cycle 19, however, the ACIS CONTAM model has also been updated, and there are considerable changes in the ACIS predictive estimates from the last cycle.
The model OBS_IDs and the ARF-building scripts have now been standardized for Chandra PIMMS calculations. Hence the procedures are the same as with cy18.
The Cycle 19 PIMMS Effective Area Public Information describes how the effective area files were generated, including the new HETG and LETG GREFFs and the new HRC-S QE file.
Effective area plots are provided for the following detector configurations:
