Matching CIAO and CALDB Versions

CALDB 3.5.0 should not be used unless you are running CIAO 3.4 or CIAO 4.0.

Are your versions mismatched? Time to update CIAO and CALDB!

Chandra Proposal Planning

These calibration files, released on 15 December 2007, are intended for use during the the Chandra Cycle 10 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.
