Association of Calibration Exposures

The association process creates an output table that contains the following columns:

A character column labeled :SCI containing the names of the scientific frames. These names are extracted from the column :FILENAME of the OST
A character column labeled `exptype' (i.e DARK, FF, etc) containing the names of the associated exposures
An integer column QUAL_`exptype' (i.e QUAL_DARK, QUAL_FF, etc) containing for each associated frame its quality flag. The calibration matching the ``first choice" set of criteria get a quality of 1 while the exposures matching only the ``second choice" set of criteria get a quality of 2.

The commands :

ASSOCIATE/IMA susi_ost bias bias_rule susi_asso C 2
ASSOCIATE/IMA susi_ost ff ff_rule susi_asso A 2

associates with each scientific frame two dark exposures by applying the rules stored in the table bias_rule, two flat field by applying the rules stored in the table ff_rule and stores the result in the table susi_asso (Table ).
