IDL programs for SAM+SAMI

Attention: The astron IDL library is used to read/write FITS files and
manupulate their  headers.  It must be accessible.  Test by compiling:
IDL>.r readfits

>>> biascor.pro 
   Reads multi-extansion FITS file, subtracts overscan (polynomial fit
   in Y), joins the quandants and writes as single image

Example: 
dir = 'data/'
biascor, dir, 'soar20140304.256'
biascor, dir, 'soar20130929.015'

>>> dcombine.pro
  Combines dithered images, correcting for distortion. The
  median-combined image is saved in FITS file, the cube of re-centered
  images is also saved, unless /nocube keyword is given.


Example:

dir = 'data/'
num = 62 + indgen(5)
imlist = 'mzfsoar20130621.'+string(num,format='(I03)')
outname = 'M5-cent-i'
dcombine, dir, imlist, outname

>>> quad.pro
  Same as bias.pro, but only median overscan is subtracted (no
  polynomial in Y). 

Example: 

dir = 'data/'
quad, dir+'soar20130929.015'

>>> samiwarp.pro
   Correct distortion and write the image with 'd' prefix. Missing
   values are replaced by zero.

Example:

dir = 'data/'
samiwarp, dir, 'mzfsoar20130621.062'
