Top-left: distribution of the maximum ASAS-3 V magnitude observed for the known Galactic RCB stars (red, see Table 1) and the 23 new RCB stars (blue, see Table 4). Bottom-left: same distribution but corrected for interstellar extinction using the Schlegel et al. (1998) reddening map and R_V = 3.1. (ASAS-RCB-9 was not plotted here as we considered its reddening value to be overestimated and not valid.) Top-right: reddening E(B − V) for the two lists of objects.
