DESCRIPTION

       This  recipe  determines  the  optical  distortions  and  the  slitlets
       distances.

       Necessary input are: Several (usually  75)  raw  frames  classified  as
       FIBRE_NS  Standard (an ´ON´ and an ´OFF´) flat frames having classified
       as FLAT_NS Standard (an ´ON´ and  an  ´OFF´)  arc  lamp  frames  having
       classified  as  WAVE_NS  A corresponding (band) reference arc line list
       classified as  REF_LINE_ARC  A  reference  table  with  data  reduction
       parameters classified as DRS_SETUP_WAVE.

       Basic documentation about the EsoRex program can be found at the esorex
       (1) man page.

       It is possible to call the pipelines from python using  the  python-cpl
       package.    See   http://packages.python.org/python-cpl/index.php  for
       further information.
