[McIDAS #VQU-472558]: imgcopy UNIT parameter



Hi Carol,

re:
> REFL doesn't seem to work.

Did you use IMGPROBE to see what the valid calibration units are
available for the image(s) you are working with?  

For instance, I just ran the following for a GOES-16 Channel 13
(IR) image:

IMGPROBE MODE=N DAT=RTGOESR/FDC13 LAT=0 75

     Image Name           Day      Nominal Time   Scan Time    Band
  ----------------      -------    ------------   ---------    ----
  RTGOESR/FDC13.0      5 Dec 18339   22:30:32      22:35:06      13

                        File     Nominal  Image     RAW         RAD         
TEMP        BRIT
       Lat/Lon      Line/Element  Line/Element                   *          K
-0:00:24 / 75:00:40   2712/ 2711   10849/10845           1953      87.664      
288.82          82
 *   milliwatts/meter**2/steradian/(cm-1)

IMGPROBE: Done

And the following for a GOES-16 Channel 01 (Vis) image:

IMGPROBE MODE=N DAT=RTGOESR/FDC01 LAT=0 75
     Image Name           Day      Nominal Time   Scan Time    Band
  ----------------      -------    ------------   ---------    ----
  RTGOESR/FDC01.0      5 Dec 18339   22:30:32      22:35:06       1

                        File     Nominal  Image     RAW         RAD         ALB 
        BRIT
       Lat/Lon      Line/Element  Line/Element                   *          %
-0:00:24 / 75:00:08   5424/ 5423   10849/10847             47      12.232       
 1.84          35
 *   watts/meter**2/steradian/micron

IMGPROBE: Done

re:
> Maybe BRIT is the best choice for visible channels?

BRIT is supported for any/all images supported by McIDAS.  The other
units supported by, say, IMGCOPY are the ones that are listed in 
IMGPROBE output.

Cheers,

Tom
