NUMBER: 349 MODULE: astutil.pdm SYSTEM: -V2.10.4p2 DATE: Tue Oct 1 16:49:49 MST 1996 FROM: valdes BUG: When there are fewer than 100 input data points the calculation of theta is incorrect. This is because the calculation does not take into account use of overlapping period bins for the small N case. The theta plot values will be incorrect (negative) but the shape appears to be approximately correct. It is not clear how the error acts in detail. One workaround is to increase the number of data points, say by replication, to greater than 100 points. Note that the shape of the theta curve will be different even if the error was not present because of the change in binning from overlapping bins to non-overlapping bins. STATUS: Fixed for the next release.
