Description
During Cycle 14 a total of 113 HST orbits were secured to observe five
isolated dwarf galaxies, namely Tucana, LGS3, LeoA, IC1613, and Cetus.
The aim of the project is a full characterization of the stellar content
of these galaxies, in term of their SFH, radial distributions, halo
populations and variable stars. Deep (V~29) F475W, F814W data allowed us
to fully sample all the evolutionary phases from the tip of the Red
Giant Branch (RGB) to well below the old Main Sequence Turnoff (MSTO).
Here we describe the observational design, and the reduction and
calibration strategy adopted. A comparison of the results obtained using
two different packages, ALLFRAME and Dolphot, is presented.
