     46 * Removed magic requirement from LAP processing.  This has allowed the processing rate to increase somewhat, as runs can now complete without waiting for destreaking to finish.
     47 * Fixed nightly science cleanup bug that was introduced with the end of magic.  We previously only cleaned destreaked data, but as no data is destreaked now, everything was left on disk.  This was fixed, and the backlog of old data was manually sent to cleanup.
     48 * Offnight diffs: checked the database for potential offnight diff pairs, and discovered that we should have created far more of these than we currently are.  This appears to be an issue with difftool not allowing multiple diffs to be created with the same input warps.  This will require some development work in the nightly science script to fix.
     49 * Background: Tracked down the bulk of the background issues observed in the stacks to cell-to-cell discontinuities that distort the background model.  The improved gradient restoration implemented last year in the row-to-row PATTERN.ROW correction seems to have improved this, but not to the point of completely resolving the issue.  The proposed solution is to artificially offset each cell to ensure that adjacent cells have similar boundary values, and then fit the smooth background that remains.  Working on coding this correction.
