Surveyed area of ≈550 square degrees in the Centaurus group. The individual DECam fields are represented by circles. The colors indicate the three different sets of data; the fields around M 83 were discussed in the MJB15 study and are shown as black circles. The blue and red fields were observed in 2014 and 2015, respectively, and analyzed for the present paper. The small black dots are the known dwarfs in the Centaurus group listed in the Local Volume Catalog (Karachentsev et al. 2004, 2013) complemented by the recently discovered nine dwarfs of Crnojević et al. (2014, 2016). The larger black dots are the two dominant group galaxies M 83 (13^h37^m00.9^s, −29^d51^m56^s) and Cen A (13^h25^m27.6^s, −43^d01^m09^s).
