I ran a good-sized test of the photometry using one of the r-band flat-field correction dithers. I needed to address a number of small bugs caught in that processs. Eventually, the full analysis completed without errors, and the results look very encouraging. The flat-field correction determined from that analysis is quite similar to the pattern observed by Eddie Schlafly in the difference between PS1 and SDSS photometry from 3pi data (reported at Harvard). Since the merge was complete, I have been running the complete set of filters of the flat-field correction data taken in late June 2009. A little work is needed to update the flat-field correction system since we changed the was 'addstar' is run in the pipeline. I expect that to be done by Monday, so that we can start processing with the improvements by Tuesday. |
