       visir_img_trans - Instrument Transmission recipe


       esorex visir_img_trans [OPTIONS] FILE.sof


       This  recipe computes the transmission at different wavelengths by comparing the flux of a
       bright star for different observations.

       The   files   listed   in   the   Set   Of   Frames    (sof-file)    must    be    tagged:
       VISIR-transmission-file.fits IM_TEC_TRANS The resuts are given in a table.


       Note  that  it  is possible to create a configuration file containing these options, along
       with suitable default values. Please refer to the details provided by the 'esorex  --help'


       The  full  documentation  for the visir pipeline can be downloaded as a PDF file using the
       following URL:


       An  overview  over  the  existing  ESO  pipelines  can  be   found   on   the   web   page

       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 for further information.
