GSC 2.4.1
Anticipated GSC 2.4.1 coverage with original GSC233 in grey and additional catalogs overlaid in color: SDSS-DR13 (blue) + VHS-DR4 (green) + ATLAS-DR3 (red) + VIKING-DR2 (yellow) + 2MASS-6x (purple) + KIDS-DR3 (cyan).
Other catalogs included as part of GSC 2.4.1 are all-sky (; ie, GAIA-DR1, UCAC5, 2MASS-PSC, 2MASS-XSC). Note that all UCAC5 are GAIA-DR1 sources.

GSC 2.4.2
GSC 2.4.2 includes additional catalogs improving coverage as can be seen below. For clarity we omit those included as part of GSC 2.4.1 (above). New catalogs include: PanSTARRS-DR1 (blue), SkyMapper DR1 (red), and GALEX AIS (green)

NIR 12-18 mag Sources
The current sky coverage for GSC 2.4.2 is below. Scale is logarithmic with log10(sources/square) degreeNIR mag refers to the first magnitude present in the list J, H, Y, Z, z, Npg, i, Ks, K (lower case z, i from SDSS; Npg is photographic). This is roughly in order of proximity to J.
