VizieR Online Data Catalog: SkyMapper Southern Sky Survey. DR4 (Onken+, 2024)

The SkyMapper telescope operates at Siding Spring Observatory (SSO), near Coonabarabran, New SouthWales, and was inaugurated in 2009.

We present the 4th data release of the SkyMapper Southern Survey. The data set is nearly complete relative to the original public Survey plans; for the first time, the release includes data taken with SkyMapper for other science programmes, such as the SkyMapper Transient Survey (SMT; Scalzo et al., 2017PASA...34...30S), and ∼6 000 very short exposures on each of seven standard fields. Improvements in sky coverage and data processing should enhance its usefulness compared to previous releases.
