preproc - makes a trimed image and linearizes the data

>prepoc *.imh trim="[179:234,1:255]" lincor1=1 lincor2=0.0441 lincor3=1.416

_____________________________________________________________________________
Making the flat-field images:

mkflat - constuct flats from on/off pair of dome flats

>mkflat @onlist @offlist hflat.avg
______________________________________________________________________________
Wavelength and geometic correction:

combine object observations to make sky
dark subtract and flat-field

>distcor eso.sky
______________________________________________________________________________
Extracting the telluric correction star
make a list of the star images

>teluric tlist star hflat.avg geomap=eso.sky

run again on groups of the same star

when finished with all groups imdel t//@tlist
______________________________________________________________________________
Object reduction:

>abba n1.17. 79 90 esoa. 1 hflat.avg eso.sky

or

>aba
_______________________________________________________________________________
Combining the twod spectra:

make a file with a list of the image name DO NOT PUT ON THE .imh.
Name the output file with a .aln extension

>getshifts eso.list > eso.aln

edit the output file to remove the junk

make a mask image of the bad pixels using imreplace and the flat-field image

>qcomb eso.list eso mask
