UVIT Calibration Database

The UVIT calibration database (CalDB) contains the data-sets (fits files) required for the calibration of UVIT data products. The CalDB is required for the UVIT Level-2 data pipeline software to generate astronomical images from the Level-1 data sets. Level-2 pipeline is an automated processing chain and as far as CalDB is concerned, the only user input parameter is the location of CalDB in the file-system.. End users are not required to be familiar with the contents of the CalDB. If you wish, you may consult the CalDB documentation from the links available on the right menu panel. The calibration database is available online from the download area.

CalDB releases

The latest CalDB release is 20170719. It will be updated periodically, based on the in-orbit calibration and monitoring. For end users, it is recommended to download a CalDB release closest to your UVIT observing run. An online tool, CalDB Select may be used to choose and download the appropriate CalDB release for your data.
