Using the FEROS software on-line at the telescope

This section briefly describes the on-line operation of the FEROS software at the ESO 1.52m telescope. For a full documentation of FEROS see:

The FEROS on-line DRS allows a complete reduction of the science spectra taken during the night from the CCD system. The on-line DRS is based on the MIDAS context feros.

To install the on-line software after the DRS is installed, the MIDAS programs of the directory

$MIDASHOME/$MIDVERS/stdred/feros/locproc

have to be copied to the local midwork directory.

After CCD readout, the BIAS program

The loadccd program itself

According to the four possible exposure types (FLATFIELD, CALIBRATION, DARK, and SCIENCE) given in the descriptor EXPTYPE, the autoreduce program starts the following actions:

This standard reduction is controlled by the FEROS context keywords which can be listed together with their current contents by the command SHOW/FEROS and are set with the command SET/FEROS key=[value]. See below for useful keywords to be used during the observing session.
