NUMBER: 179 MODULE: daophot.allstar SYSTEM: V2.10 DATE: Wed Sep 16 14:37:46 MST 1992 FROM: davis BUG: If 1) cache=no, or cache=yes and memory preallocation fails for one or more of the data, scratch or weight arrays, 2) one or more of the groups has greater than maxgroup stars, 3) regrouping is performed on the too large group and 4) the first star in the next non-regrouped group has a y value less than the y value of the first star in one of the regrouped groups, allstar can fail with an 'attempt to access the scratch, weight, or data pixels randomly' error. STATUS: The bug is fixed in 2.10.2. Possible work arounds include: 1) setting cache=yes instead of no if the machine has enough memory and swap space 2) setting the maxgroup parameter to a larger value than the default value of 60 3) decreasing the fitting radius somewhat since this affects the grouping process.
