 Description   

Medium res. red images are distinguished by having arm = 4 instead of arm = 2. The ccdActor needs to add support for writing those and for distinguishing when to do so. A keyword from the rexm is probably the best idea, though I'm not sure what to do if that is not available. Assuming arm=2 is probably the best bet.

There is an existing keyword for that :

Key('rexm',
    Enum('low', 'mid', 'undef', name='position', help='rexm current position')),

Good. A couple of things:

  • Can you at some point add `FITS=('W_ENRGRT', 'ENU_RED_GRATING')`. (or something)
  • Will that device always be powered up, or will this fall under INSTRM-215?

Key('rexm',

 help='rexm current position',
 FITS=('W_ENRDAP', 'ENU_RDA_POSITION'))),

I will go for RDA (from the product tree) it stands for Red Disperser Assembly

Defaults to low res if end.rexm cannot be read or has a bad value.
Can be overridden with setGrating @(low,med,real), where real says to use the enu keyword.
