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
