Sky Distribution

Since MaStar observations are conducted by piggybacking off of the APOGEE-2N survey, MaStar science targets are mostly restricted to APOGEE-2N fields, except for a few MaStar-specific fields. In the images below, each individual black dot represents one MaStar science target.

This release of MaStar data also includes spectrophotometric standard stars targeted on MaNGA plates. For the sky distribution of those stars, please refer to the MaNGA survey footprint page.
