Observing with LUCIFER
The normal observing operation with LUCIFER is entirely performed through scripts (Sect. 7.4).
The interactive observing mode (Sect. 7.3) is described in detail here since it allows to introduce the
definition of all parameters needed for scripts.
Login and Software Start
Usually, the Lucifer control software (LCSP) is running continuously on the SUN V880 workstation.
That means the observer has only to start the necessary GUIs. Therefore he/she has to use the
dedicated LBTO linux machine and open a NXClient connection with the following parameters:
• User name: observer
• Password: provided at the LBT
• host: sun-luci
After being connected to the SUN X environment, double click on the Start LUCIFER icon on the
desktop. This will open all the necessary GUIs for the observations.
The readout software initial panel requests you to press on OK. With the exception of the observer
name that you can specify there, to see it updated in the FITs header, do not change any other of the
settings. Also Do NOT close any of the terminal window that opens automatically.
Start and end of night procedures
Start of night
• Set a new directory (path file) in the Readout Manager GUI (Fig. 22)
• Set a new filename (change the date) in the Readout Manager GUI (Fig. 22)
• Save a dummy image to stop the archive complaining it has nothing to archive
• If the sky is clear, go on with taking twilight sky flats (at zenith before sunset); see section 6.6.1
• Then move on with the pointing correction procedure; see paragraph 5.2
End of the night
• Put the two blind filters and the N1.8 camera in position and set the detector to DCR mode
with DIT=2sec (manual saving) while the operator is closing the telescope
• Start the flush detector.txt script
• Prepare your scripts to take the dark calibrations
• Once the dome is closed and dark (no light), the telescope at zenith, rotator angle = 341 and
the guide probe has been parked, you can take the needed calibrations with the calibration unit
• When done with the calibration unit, set again the two blind filters and run the flush detector.txt
script again
• Put the BLIND mask in FPU and start your dark calibration script
