Top: CMD of our spectroscopic sources overlayed on the sources from Catalogue 1 of Paper I. Red squares are C-type stars, blue triangles are M- and K-type dwarf stars and the green hexagon is the only M-type giant in our sample. The solid lines represent criteria I proposed by Kacharov et al. (2012). Bottom: same CMD as above but the solid lines now represent criteria II proposed by Kacharov et al. (2012). Regions in both CMDs have been labelled in accordance with the CMDs of Kacharov et al. (2012).
