The Sagittarius dwarf irregular galaxy (SagDIG): distance and star formation history
The distance, star formation history and global properties of the Local Group dIrr galaxy SagDIG are derived based on an [I-(V-I)] colour-magnitude diagram of ~ 1550 stars. A distance of 1.06+/- 0.10 Mpc is obtained from the I magnitude of the TRGB. This corresponds to 1.17 Mpc to the barycenter of the Local Group and 1.34 to M 31, being DDO 210
