  We present CCD photometry and proper motion studies of the two open star
clusters NGC 1960 (M 36) and NGC 2194. Fitting isochrones to the colour
magnitude diagrams, for NGC 1960 we found an age of t=16 Myr and a distance of
roughly d=1300 pc and for NGC 2194 t=550 Myr and d=2900 pc, respectively. We
combined membership determination by proper motions and statistical field star
subtraction to derive the initial mass function of the clusters and found
slopes of Gamma=-1.23 +/- 0.17 for NGC 1960 and Gamma=-1.33 +/- 0.29 for NGC
2194. Compared to other IMF studies of the intermediate mass range, these
values indicate shallow mass functions.
