NUMBER: 333 MODULE: daophot.psf SYSTEM: V2.10 DATE: Wed Mar 20 13:59:27 MST 1996 FROM: davis BUG: If the daopars function parameter is set to auto and the best fitting function is either moffat25 or moffat15, the psf model look-up tables if any will be computed incorrectly. The problem occurs because only the 3 fitted parameters (the beta parameter is held fixed) are being saved and restored correctly. The array element that should hold the fixed beta value is instead occupied by the equivalent parameter for the last computed function the penny function. STATUS: Fixed for the next release of iraf and in the version of daophot in the external addon package digiphotx. The workaround is to run psf twice, once to determine the best fitting function (as this is being determined correctly), and then again with the function parameter set to the selected function.
