Planet occurrence rate (color coded) as a function of metallicity and stellar mass in our Lick sample; only the secure planets have been considered. Data have been heavily smoothed, so that the general trend in planet occurrence rate becomes apparent. There is a clear maximum in planet occurrence rate for metallicities of about 0.2 and masses of about 2 M⊙.
