M83 Mosaics ("M83MOS")

Galaxy M83 (NGC 5236) is a face-on spiral galaxy with a starburst in its nuclear region and active star formation occurring throughout its spiral arms. The M83 mosaic project, led by William Blair (Johns Hopkins University) and archived as a High Level Science Product at MAST, created mosaics spanning seven fields using WFC3-UVIS and WFC3-IR. Two of the fields used in this project were obtained during Program 11360 (PI: R. O'Connell) in 2009, while the other five fields were obtained as part of Program 12513 (PI: W. Blair) in 2012. Each of the 15 filters across the seven fields are combined into a single mosaic of M83, although the Fields 1 and 2 include additional filters, and hence the mosaics for those contain only those two fields. All of the mosaics, however, are astrometrically aligned to a common reference.
