Launching VDAT is easy:
vdat [-h] [--rawdir RAWDIR] vdat_setting.cfg
The configuration file vdat_setting.cfg, together with any other file needed by VDAT, is shipped with the code and can be retrieved using the vdat_config command described here.
The value of --rawdir should be the name of a directory containing fits files organized according VIRUS standards as in Raw directory structure. If provided the fits files in RAWDIR are symlinked into a redux directory, defined in the vdat_setting.cfg file, described in Redux directory structure.
If the --rawdir is not provided, it will look for the redux directory. It it doesn’t exist, the execution aborts.
Warning
Currently this is the only way to feed data into VDAT.
Here we describe the GUI with screen shots and what it’s possible to do
