Cycle 16 PIMMS Effective Areas

Return to: Proposal Planning Index

Released as of 12 DEC 2013

---

The PIMMS Effective Areas for Cycle 16 include upgrades for the HRC-S QE, the HETG GREFF first orders, and the LETG GREFF higher orders. As is always the case, the time-delay factor for the ACIS contaminant build-up has been updated for cy16.

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 cy15.

The Cycle 16 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:

• ACIS-I
• ACIS-S
• HRC-I
• HRC-S
• HETG/ACIS-I
• HETG/ACIS-S
• LETG/ACIS-I
• LETG/ACIS-S
• LETG/HRC-I
• LETG/HRC-S
