KK 153 in the context of the confirmed dwarf galaxies in the P24 database. Upper panel: M_V vs. log r_h. Points are colour-coded according to the stellar mass derived from the integrated V luminosity adopting M/L_V = 1.0 (while in the original P24 list M/L_V = 2.0 is adopted). Lower panel: M_V vs. log M_H I for the P24 dwarfs that have a valid measurement of the H I mass. The points are colour-coded according to their H I mass to stellar mass ratio. In this case M/L_V = 1.0 was adopted as well. In both panels KK 153 is highlighted with a red square.
