       naco_img_strehl - Strehl computation recipe


       esorex naco_img_strehl [OPTIONS] FILE.sof


       naco_img_strehl -- NACO Strehl Ratio recipe.

       This recipe estimates the strehl ratio and its error bound.

       The  Set  Of  Frames  (sof-file)  must specify at least one pair of files and they must be
       tagged either NACO-raw-file.fits CAL_PSF or NACO-raw-file.fits TECH_PSF


       --star_r <float>
              The star radius [arcsecond] (float; default: 2.0). The full name of this option for
              the EsoRex configuration file is naco.naco_img_strehl.star_r [default = 2.0].

       --bg_r1 <float>
              The  internal  radius of the background [arcsecond] (float; default: 2.0). The full
              name of this option for the EsoRex configuration file is naco.naco_img_strehl.bg_r1
              [default = 2.0].

       --bg_r2 <float>
              The  external  radius of the background [arcsecond] (float; default: 3.0). The full
              name of this option for the EsoRex configuration file is naco.naco_img_strehl.bg_r2
              [default = 3.0].

       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'

       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.
