Description

This is an all-sky 1420 MHz (21cm) continuum map formed from surveys of the northern sky with the 25-m Stockert telescope and the southern sky with the 30-m Villa-Elisa telescope. The units of the map are mK TB full beam, the effective resolution is about 35', the effective sensitivity is about 50 mK TB full beam (about 3 times the rms noise), the gain scale accuracy is about 5%, and the zero level accuracy is 0.5 K.

The Centre d'Analyse de Donn���ees Etendues group used the data to form an all-sky HEALPix format map following the method described in Appendix A of Paradis et al. 2012, A&A, 543, 103, ADS. Their HEALPix map is mirrored here. The original World Coordinate System format data are available from the MPIfR Survey Sampler site.
