General Transformation Factor from Number of Stars of Tenth Visual Magnitude to Raleigh Per Angstrom Or Nano Lambert for Different Wavelengths

In the nearest neighbour method of the random distribution of N objectson a sphere surface the variable (N-1) sin²(α/2) isproposed to be used instead of the angular distance α. Thenboth the expected mean and variance equal to one for large N, and both theStudent's test and F-test are especially simple. An illustrative applicationshows that the superclusters – collected in the All-Sky Catalogues ofSuperclusters of Abell-ACO Clusters – need not be distributedrandomly.
