A friend/colleague of mine wants to be able to bin an image by 2x2 or 3x3 after the fact. I don't know of any task that will do this, but I thought I'd ask.
thanks,
phil

Hi Phil,

The answer might depend on whether he wants to have something that also updates the header as if was binned by an instrument. But just to bin "an image" there is a core task called blkavg.

Regards,
Frank
