Flat-field Correction Analysis (GPC1 2009.10)

• Generate a flat-field correction analysis run selecting an appropriate set of observations:

  set options = "-simple -dbname gpc1 -definebyquery"
  set options = "$options -set_label flatcorr.20091003"
  set options = "$options -dateobs_begin 2009-06-10T00:00:00 -dateobs_end 2009-06-14T00:00:00"
  set options = "$options -comment %sdss_radec_photcorr%"
  set options = "$options -set_workdir neb://@HOST@.0/gpc1/flatcorr.20091003"
  set options = "$options -set_dvodb /data/ipp009.0/gpc1/flatcorr.20091003"
  
  flatcorr $options -filter g.00000
  flatcorr $options -filter r.00000
  flatcorr $options -filter i.00000
  flatcorr $options -filter z.00000
  flatcorr $options -filter y.00000
  

• Apply the corrections:

  dettool -makecorrection -det_type FLATTEST -det_id 105 -iteration 0 -workdir neb://@HOST@.0/gpc1/flatcorr.20091003 -dbname gpc1
  dettool -makecorrection -det_type FLATTEST -det_id 106 -iteration 0 -workdir neb://@HOST@.0/gpc1/flatcorr.20091003 -dbname gpc1
  dettool -makecorrection -det_type FLATTEST -det_id 107 -iteration 0 -workdir neb://@HOST@.0/gpc1/flatcorr.20091003 -dbname gpc1
  dettool -makecorrection -det_type FLATTEST -det_id 109 -iteration 0 -workdir neb://@HOST@.0/gpc1/flatcorr.20091003 -dbname gpc1
  dettool -makecorrection -det_type FLATTEST -det_id 110 -iteration 0 -workdir neb://@HOST@.0/gpc1/flatcorr.20091003 -dbname gpc1
  

• Test the corrections:

  set options = "-simple -dbname gpc1 -definebyquery -mode flattest -reduction flattest"
  set options = "$options -set_label flatcorr.20091003"
  set options = "$options -dateobs_begin 2009-06-10T00:00:00 -dateobs_end 2009-06-14T00:00:00"
  set options = "$options -comment %sdss_radec_photcorr%"
  set options = "$options -set_workdir neb://@HOST@.0/gpc1/flatcorr.20091003"
  set options = "$options -set_dvodb /data/ipp009.0/gpc1/flatcorr.20091003"
  
  flatcorr $options -filter g.00000
  flatcorr $options -filter r.00000
  flatcorr $options -filter i.00000
  flatcorr $options -filter z.00000
  flatcorr $options -filter y.00000
