We have defined a set of rules for classifying SUSI exposures according to
the exposure type (BIAS, FF, SCI) and a set of rules for classifying them
according to the optical path. (In this case, this consists
simply in classifying the frames according to the filter number that was used.)
The MIDAS session shown in Table
creates these rules and applies them to our set
of SUSI exposures (Table ).
The result of the classification process is illustrated in Table .
For convenience, one may also store all the classification parameters in a table (Table ) and apply a set of classification rules in one step.
Note that instead of the interactive command CREATE/CRULE the equivalent
command WRITE/DESCR may be used.
The table must
contain the following columns:
In the session mentioned above, one can replace the four calls to the command
CLASSIFY/IMAGE by:
CLASSIFY/IMAGE susi_ost susi_rule.tbl
Table: Observation Summary Table with file classifications appended in column :EXPTYPE and :OPATH as defined and applied in Table
Table: Classification Table for SUSI exposures (susi_rule.tbl)
