The applet is computing the
angular separation (degrees) of the nearest
neighbor for 200 of the brightest stars
(visual magnitudes < 3.0):
The stars are displayed by two frames:
Splitting the celestial sphere (size 360^{2}/π square degrees = 41253 square degrees) into equalsized cells (d*d square degrees each) distance for number of stars n>240
computed by the formula
Between n=60 and n=240 the mean
difference between the observed angular distance (applet) of
the nearest neighbor and the value from
the formula is 1.7 %.
