Very good.

The reason is that the remapped images are calibrated during in the
process of creating the output image.  The original images have a calibration
block that is used to convert raw values to the supported calibration
units.

I am thinking that the image created by REMAP2 will be 'raw' like the
original.  This means that the calibration block should be available
so that IMGPROBEs will return raw, BRIT, Albedo, etc.

Cheers,

Tom
