We selected two representatives of the three main types of dwarf galaxies represented in the Local Group, i.e. two dwarf irregular and two transition type dIrr/dSph galaxies (the two closest of each type with high galactic latitude), and the two isolated dSph galaxies known to date in the Local Group. All galaxies have been observed under HST P. ID. 10505, except Leo A (P.ID. 10590, P.I. A. Cole) and Phoenix (P.ID. 8706, P.I. A. Aparicio).
