| | 42 | * Changed the algorithm psphotStack uses to choose objects to for forced photometry. Now it will be done only if the number of good detections for the object is >= 2 or if the only deteection was in y band (controllable by recipe) |
| | 43 | * Did some analysis of the source matching in psphotStack. |
| | 44 | * Implemented some changes to the detection efficiency measurements that avoids errors for inputs with a small number of pixels. |
| | 45 | * Ran a sample of 167 LAP skycells through the current version of psphotStack. All but 3 succeeded which is much better than we have ever done before with these data. Fixed a bug that allowed one of the others to succeed. The remaining two have psf matching problems that need to be investigated. |
| | 46 | * Modified psphotStack to remove forced photometry sources for which an aperture flux could not be measured. This happens if all of the pixels are masked. This should reduce the number of useless stack detections in PSPS significantly. |
| | 47 | * A user submitted some detectabiltiy query requests to the postage stamp server. They did not work. I introduced a trivial bug back in February that caused all detectability queries to fail. No one noticed. Fixed that and some of his requests ran into problems. He also reports that it is difficult to match up the results to each of his requests. We need to tweak the interface a little. I plan to work on that next week. |
