| | 8 | We have largely been working to iron out wrinkles and issues as they come up, with special effort on the overall detection efficiency. We've been interacting a lot in the past 2-3 weeks with the MOPS team, and finding a number of interesting issues. Paul has been worrying about the most important of these: an error in the covariance calculation which was preventing the diff detection from reaching as deep as it should have been. With that error identified and corrected (as well as a related error in warp due to the change of pixel scale), he has been trying to understand the impact of the fix on the magic masking. We will need to iterate with Paul Sydney for final validation, but we can test the magic impact with the magic verification data set used before the start of Demo month. It may be necessary to tweak the magic threshold to reach the right balance between excess streaks and catching all real ones. |
