Description:
MAST hosts a copy of the SkyMapper DR4 catalog.
SMSS DR4 contains optical photometry in the 6 SkyMapper filters (u,v,g,r,i,z) for ~700 million astrophysical sources over 26,000 sq.deg, ranging from the South Celestial Pole to Dec=+16 degrees for objects with data in all bands, and some sources as far North as +29 degrees. The photometry is drawn from over 15 billion measurements made from more than 400,000 images acquired by the 1.3m SkyMapper telescope between March 2014 and September 2021. The typical 10-sigma depths for each field range between 18.5 and 20.5 ABmag, depending on the filter, but certain sky regions include longer exposures that reach as deep as 22 ABmag.
Compared to previous SkyMapper data releases, DR4 includes significant enhancements in data processing, most notably a new photometric calibration anchored to synthetic photometry from Gaia low-resolution spectroscopy, which resolves reddening- and spatial-trends identified in previous releases, especially in the bluest filters, u and v.
A large number of other photometric and spectroscopic surveys have been cross-matched to the dr4.master table of objects, to facilitate various scientific investigations.

Description:
The Millennium Galaxy Catalogue (MGC) is a 37.5 deg2, medium-deep, B-band imaging survey obtained with the Wide Field Camera on the INT. The survey region is a long, 35 arcmin wide strip along the equator, covering from 10h 00m to 14h 45m and is fully contained within the regions of both the Two Degree Field Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS).

Description:
MINIJ-PAS PDR201912 Catalogue (December, 2019) is based on scientific images in 60 filters covering a total area of ~1 square degree. MiniJ-PAS is a 60-band photometric optical survey based on images collected by the JST250 telescope and the Pathfinder instrument at the Observatorio Astrofísico de Javalambre (OAJ, Teruel, Spain) .

Description:
MUDEHaR DR1 (March, 2025). MUDEHaR (MUlti-epoch Disparity Examination of H-Alpha and infraRed) is a multi-epoch photometric survey of two narrow filters: Hα and the calcium triplet window. Using the JAST telescope and T80Cam instrument at the Observatorio Astrofísico de Javalambre (OAJ, Teruel, Spain) is studying 40 square degrees of star forming fields in the Galactic disk. It will detect all kind of variable Hα stars on a days-months-years scale. .
