Hello

Is astronomical image processing done in a linear space or a gamma
space?

Normally in linear space, Mike - because you are primarily interested in
physical quantities and their quantitative results.

After that has been achieved, the representation for human consumption
is created - either from the source data or the processed data depending
on the objective required.
