GAMA-KiDS colour scheme

  • Ghost_Sheep_SWR by Ghost_Sheep_SWR

    I was wondering if it is possible to give a short explanation of the colours we see in the GAMA-KiDS images, and maybe how they compare to other surveys such as SDSS and DECaLS.

    Blue means starforming for example? Or are there typical artifacts that are difficult to distinguish from real features, typical asteroid images etc.

    These are 2-colour images, cyan and amber. Cyan is blue for starforming. amber is for the red stars. But green will be poorly represented, more as a yellowish green.

    It has more resolution than SDSS, and less than the CFHT. I'm not sure about DECaLS, maybe about the same? and less than HST.

    We will have to learn about what artifacts are seen.
