This chapter provides a detailed description in terms of manual pages of the panels, scripts and the options available for the CCD stand-alone.
3.1 Panels
"File" menu

exit the application
"Options" menu
"context sensitive"
If selected, buttons are enabled/disabled according to the current
context. If not selected, all buttons are enabled, independently
from the current status of the system.
"complete FITS"
If enabled, the HIERARCH FITS information, normally saved in a
separate ASCII file, is merged into the image FITS file
"archive"
If enabled, the CCD stand-alone sw informs VLT archive about new
image data available whenever a new image is saved on disk.
"Utilities" menu

It calls the sprBrowse utility. Enabled only in those environment
where this utility is available and in the search PATH for
executable.
"Show Configuration"
The current values of the configuration parameters, as stored
in the on-line database, is shown through the panel ccdConfig.
"Maintenance" menu
"Edit Configuration"
The current values of the configuration parameters, as stored
in the on-line database, is shown through the panel ccdConfig
and can be modified
