BIASes are called : *Dark*
FFs are called : *FlatSpec*
Arcs are called : *HeAr*
Science spectra are called : *EFOSC_Spectrum*obj*
And the wavelength calibration is done by:
In turn, waveguess displays the solution using
Now during the night, each time you get a new spectrum, you can go ahead with the following steps.
Of course, this will first subtract the BIAS, divide by FF, trim the image, etc. (all the stuff that was done for the calib images).
The spectrum is extracted taking the extraction windows for the object and the sky from the file obdef.dat (a template is created by @@ defaultpars). The file looks like this:
Which will find the response curve. By default, the response function is fitted with a polynomial of degree 12.
