NUMBER: 247 MODULE: photcal.fitparams SYSTEM: V2.10 DATE: Mon Jun 13 16:12:33 MST 1994 FROM: davis BUG: If the fitparams task parameter weighting is set to 'photometric' or 'equations', the addscatter parameter is set to 'yes', and either the number of parameters to be fit equals the number of data points, or the fit has no scatter, fitparams will crash with a floating operand error. This occurs because the expression used to estimate the additional scatter to be added to the weights in the next iteration of the fit goes to 0 in the denominator, causing a divide by zero error. STATUS: The bug is fixed in 2.11. The workaround is to set weighting to 'uniform' or set the addscatter parameter to 'no'.
