GEMINI-GMOS (left) and SDSS DR12 (right) g′ images of the LSB galaxies located, in projection, within the halo of NGC 3193 (top, 90.3 arcsec on a side; dSph1) and between NGC 3189/3190 and NGC 3185 (bottom, 250 arcsec on a side; dSph2). For clarity, we added level contours in the case of the SDSS image of dSph1. The images of SDSS DR12 have been processed with the IRAF task boxcar considering a box of 10 × 10 pixels. As in Fig. 1, North is up and East to the left.
