Hello again
After all, we are prepared for actual processing so I would like to write something about basic steps of data reduction in IRAF which should be applied to all kind of data (photometric, spectroscopic..). These steps are focused on removing the detector 'finger print'.
***NOTE***
I was working with data from ESO archive, obtained from ESO VLT, specifically from its UVES spectrograph. For this reason, all the examples will be for echelle spectra from ESO. Though, main differences for other kinds of data will not be very relevant in this part of processing.
