Initialization of the DRS at the beginning of the night

To use the automatic data reduction as described above, the DRS has to be initialized at the beginning of the night.

For this purpose several flat-field and wavelength calibration exposures have to be taken in the Object-Sky mode of FEROS before the beginning of the night following the following sequence:

Now the following initialization steps are performed

With this step completed, the FEROS on-line DRS is initialized.

Every new incoming spectrum will be saved and reduced now as described above.
