NUMBER: 159 MODULE: images.imstatistics SYSTEM: V2.9 DATE: Fri Oct 11 13:54:19 MST 1991 FROM: davis BUG: The computed value of the kurtosis was 1.0 too small, i.e. a Gaussian distribution would have a computed kurtosis of -1.0 instead of 0.0. STATUS: The bug has been fixed in IRAF 2.10. The workaround is to add 1.0 to the computed value of the kurtosis.
