Description:
Opens
a GSD file for reading, and checks the version (currently only supports GSD Version 5.3).
The data are converted to ACSIS format and written to disk. Metadata are converted to
appropriate FITS headers.
Parameters:
DIRECTORY = _CHAR (Read)
Directory for output
ACSIS files. A NULL value will use the current working directory. This command will
create a subdir in this directory named after the observation number.
IN = CHAR (Read)
Name of the input GSD file to be converted.
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]
OBSNUM = INT (Read)
Observation number for files prior to Feb 03. For newer observations this parameter is not
required. Default value will be the observation number read from the file but prior to Feb 03
this number was the number within the project rather than the number from the night
and may lead to name clashes since ACSIS data are numbered for a UT date.
Notes:
-
Whilst this command does a reasonable job of converting common data to ACSIS format it still has to
undergo extensive testing to ensure that it is always doing the correct thing. Testing of this command
and comparing its results with SPECX maps will be welcomed.
-
The ORAC-DR recipe defaults to REDUCE_SCIENCE. The exceptions are as follows:
-
REDUCE_SCIENCE_CONTINUUM for solar-system objects (Sun, Moon, planets, Titan);
-
REDUCE_POINTING for a FIVEPOINT observation type and a DAS backend;
-
REDUCE_FOCUS for a focus observation type; and
-
REDUCE_SCIENCE_BROADLINE for objects with radial velocities above 120 km/s.
