GSD2ACSIS - Convert a GSD format DAS data file to an ACSIS format NDF

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.

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.
