VizieR Online Data Catalog: HST emission line survey of Andromeda. I. Be stars (Peters+, 2020)

We observed M31 with the Hubble Space Telescope (HST) in the 12 orbit GO-13857 program (Dalcanton PI). Pure-parallel observations were made with the Advanced Camera for Surveys/Wild Field Camera (ACS)/(WFC) and WFC3/UVIS (UV-visible) camera at three distinct spatial locations that coincided with regions of the galaxy previously observed via the HST/PHAT (Panchromatic Hubble Andromeda Treasury; Dalcanton+ 2012ApJS..200...18D) survey, yielding six distinct pointings across M31. We obtained a second epoch of observations of these same six pointings approximately 1yr later (in 2015), when HST was able to achieve the same view of these pure-parallel pointings. Observations were made in both cameras using the F658N narrow-band filters and using the F625W broadband filter. A summary of our basic observational design is provided in Table1.
