Hello everyone,
I find myself in quite a pickle. Here is the situation: I took, a while ago, a number of light frames with a CMOS OSC camera binned 2x2. The corresponding flats however were taken in binning 1x1 (that happens when you forget what you did the past night when taking sky flats the following evening!). There is no question of re-doing the flats has that particular horse has already bolted. Trying to find some way to do the software binning "after the fact" in PX resulted in nothing, as far as I can tell. Conceivably, I could split the light frames in the RGB components after debayering, do the same with the master flat, bin the RGB-splitted flats and use them to flatten the RGB light frames. Which seems quite a lot of work. Or, there maybe some of you who can suggest a PixelMath trick to achieve the binning of the raw master flat so that it would work directly on the raw light frames. I can do that outside PX (say in Mathematica or Matlab) but would prefer to avoid it if I can.
Thanks
Andrea
