Sectors 20 and 21 will be replaced with newly exported data files starting . While the ingest is taking place, the data files will be a disparate set of both the original and the new files. Once the ingest is complete the check boxes in the data holdings table below will be replaced with 'v2'.
The reasons for this re-delivery include changing how the data quality flags for stray and scattered light are set. It also includes a correction to the time and to the FFI collateral pixels. For more information, see the 'Memo' listed next to the data release notes for DRN27 and DRN29. It also includes information on how one can tell the difference between the new and old files.
