This project is for the calibration matching logic for Gemini data. This logic is handled via per-instrument calibration definitions. The matching rules are expressed as SQLAlchemy database queries against a DRAGONS maintained sqlite database.
When you have a calibration file that doesn't match a target file when you
expect it to, this library provides the tool calcheck for inspecting the
query for mismatches to diagnose it. It does a best-effort job but can be
helpful. You can supply auto to infer the calibration type, or you can
replace auto below with flat, bias, etc.
Useage: calcheck auto
Unfortunately, this project still has some dependency on DRAGONS, which in turn
depends on GeminiCalMgr. The DRAGONS dependency stems from the use of
astrodata to read the FITS files. The astrodata objects are also used as
inputs to the calibration logic.
Two possible long-term solutions would be to break out the astrodata from
DRAGONS as a separate library, or integrate this GeminiCalMgr project directly
into the DRAGONS codebase.
