| | 48 | * LAP: defined new areas for processing, and finished testing of new code. Identified common failures that are caused by reprocessing: |
| | 49 | * chip stage: due to bad shuffles in the past, some nebulous keys do not have two good instances. This causes errors when the bad instance is selected for processing. I've developed a work around, and will be implementing a permanent fix for this problem in the future. |
| | 50 | * warp stage: as we are now updating data instead of launching a new processing, we can occasionally create warp skycells that are unusable in stacking because they do not have a PSF. This appears to be a result of the destreak process masking the small number of PSF stars on the image. This case is now detected and the quality of these skycells set to reflect the bad data quality. |
| | 51 | * stack stage: we occasionally orphan stacks by cleaning up the data. This happens because the stack faults, the LAP code detects that all stacks have been attempted, and triggers the cleaning. As these faulted stacks may not ever complete correctly due to code issues, this seems to be the correct solution for the moment. |
| | 52 | * Diskspace: work on increasing the reliability of the shuffle code. No great improvement, although there is some evidence that the shuffle is slowly freeing space on the most full disks. |
| | 53 | * Stacking: Looked into how the stack PSF is determined, as we have good evidence that the output PSF in the convolved stacks is larger than expected based on the set of input warps. No conclusion yet. |
