Given a set of
dark observations, calculate a mean dark frame from each. A bad bolometer mask can be supplied to
remove known bad bolometers. Does not flatfield.
BBM = NDF (Read)
Group of files
to be used as bad bolometer masks. Each data file specified with the IN parameter will be masked. The
corresponding previous mask for a subarray will be used. If there is no previous mask the closest
following one will be used. It is not an error for no mask to match. A NULL parameter
indicates no mask files to be supplied. [!]
IN = NDF (Read)
Input files to be processed.
Non-darks will be filtered out.
MSG_FILTER = _CHAR (Read)
Control the verbosity of the
application. Values can be NONE (no messages), QUIET (minimal messages), NORMAL,
VERBOSE, DEBUG or ALL. [NORMAL]
OUT = NDF (Write)
Output dark files. These can be
used as bad bolometer masks in subsequent processing steps via the BBM parameter in
other SCUBA-2 SMURF commands.
Dark files will be subtracted from raw data
during the flatfielding step. Commands that flatfield data can use either raw dark files or the
output from CALCDARK.
