Chandra Proposal Planning
These calibration files, updated to the final CY19 release on 15 DEC 2016, are intended for use during the Chandra Cycle 19 Call for Proposals.
- ACIS RMFs and ARFs
RMFs and ARFs for specific positions on ACIS-I and ACIS-S. These files were generated from the most recent CALDB available at the start of the current proposal cycle.
- Grating RMFs and ARFs
Grating RMFs and ARFs for the HETG/ACIS-S, LETG/ACIS-S, and LETG/HRC-S grating/detector configurations. These files were generated from the most recent CALDB available at the start of the current proposal cycle.
- PIMMS Effective Areas
Technical information and plots of the effective areas used to calculate count rates in the PIMMS software.
- Chandra Effective Area Viewer
View the current cycle effective areas for the PIMMS-supported configurations, including plots and specific data values versus photon energy, and compare data from different cycles.
