FOSTAT determines empirically the distribution of electron density values on a Fourier map on the map bdf written by FOURR. The expected range of electron density values is divided into equal intervals which is assigned a storage counter. Each density point falling within an interval increments the corresponding counter. Values falling outside the specified range are also counted. FOSTAT lists the number of points in each interval; the total number outside the range; the percentages, along with the minimum value for each interval.
