Abstract: As a continuation of our project to derive the distribution and temperature of the modulating component of spots on active late-type stars, the authors have observed a number of RS CVn, BY Dra and dMe stars photometrically (optical UBV(RI)_c and infrared HJK) and spectroscopically (TiO band) simultaneously in Dec. 1996 and Jan. 1997. The simultaneity of these observations allows us to apply two of the currently available techniques with which spot temperatures, sizes and locations can be obtained, viz., the light-curve modelling technique and the TiO band technique. We present here the photometric and spectroscopic data for one of our targets, AG Dor, and the spot model that best fits the observed light and colour curves and the depth of the lambda 7055 AA titanium oxide band for this active star.
