The HEASARC Calibration Database

Caldb manager: Dr. M. F. Corcoran

The HEASARC's calibration database (CALDB) system stores and indexes datasets associated with the calibration of high energy astronomical instrumentation. The system can be accessed by users and software alike to determine which calibration datasets are available, and which should be used for data reduction and analysis. (Read more...)
