9 STANDALONE OPERATIONS: REFERENCE
This chapter provides a detailed description in terms of manual pages of the panels, scripts and the options available for the FIERA CCD stand-alone.
9.1 Panels
"General"
"Camera"
The line below shows the name of the camera according to
environment variable CCDNAME
"Type"
The line below shows if the camera is of type scientific or technical.
It is derived from the name of the clock patterns.
"ID"
The line below shows an unique identifier of the camera used.
"Chip ID"
The line below shows an unique identifier of the chip used.
"State"
The line below shows the current state of the FIERA sw.
"Simulation"
The line below shows the level of simulation the software is supposed
to run.
"Startup"
Perform a complete ("cold") startup of the whole FIERA sw.
If the software is already partially or fully running, first it is
shut-down.
It takes a few seconds.
After successful completion of the startup, the operational state
becomes on-line
"Shutdown"
Shutdown the FIERA sw. After successful completion, the operational
state becomes OFF
"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 FIERA stand-alone sw informs VLT archive about new
image data available whenever a new image is saved on disk.
"Problem Report"
It calls the sprBrowse utility. Enabled only in those environment
where this utility is available and in the search PATH for executable.
"Configuration"
The current values of the configuration parameters, as stored in the
on-line database, is shown through the panel fcdConfig.
"Engineering"
Start the engineering panel fcdei for FIERA operations.
"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.
"Observation/Maintenance"
It allows to select the level of privilege (e.g. if in observation,
the engineering button is disabled and the configuration parameters
can be shown, but not modified).
Normally to enter maintenance mode, one must have a special privilege
(e.g. password), currently not implemented.
"Setup"
"Exposure"
"Time"
Exposure time in seconds
"Options"
"Repeat"
"forever" --> infinite loop of repeated exposures
"n times" --> repeat the exposure n times
"Period"
Periodicity, in sec, for repeated exposures. If set to 0,
the next exposure is started as soon the previous one is finished.
Meaningful only for repeated exposures.
"Type"
Currently only options are Normal and Dark (the latter disabled
if the system has no shutter)
"Image"
"Save in file"
If set, the image is saved in the specified file in
FITS uncompressed format
"Display"
If set, the image is written in shared memory for Real-Time Display.
"Options"
"Type"
Type of image which is going to be produced.
Options:
"Normal". Normal case
"Bias". The image has to be saved as bias frame for processing
"FF". The image has to be saved as flat field frame for process
"Transfer"
Transfer to WS only one image out of n acquired.
Meaningful only for repeated exposures.
"Display in rapid frame"
The image is displayed in the Rtd rapid frame instead of the main
frame
"Readout"
