New estimates of the distance to these galaxies are provided [(m-M)0(UMi)=19.41±0.12 and (m-M)0(Dra)=19.84±0.14], and a comparative study of their evolved stellar population is presented. Description: The data were obtained at the 3.52m Italian telescope Telescopio Nazionale Galileo (TNG; Roque de los Muchachos, La Palma, Canary Islands, Spain) using DoLoRes, a focal reducer imager/spectrograph equipped with a 2048x2048 pixel thinned and back-illuminated Loral CCD array. The observations were carried out during three nights (2001 March 19, 20, and 21) under average seeing conditions (FWHM∼1.0"-1.4"). The first and third nights of the run were photometric. The scientific exposures taken during the second night were calibrated indirectly by using the data acquired in the photometric nights. File Summary:
