Bailout bricks in DR10 have zero-ed out RA,DEC #730

Open djschlegel opened 5 months ago

djschlegel commented 5 months ago

There are 246 bricks in DR10 that were run at the very end (Oct 4-5, 2022) with the "bailout" option when Dustin was trying to clean up the last remaining reductions. 186 of these bricks have output coordinates with RA=DEC=0, even though BX,BY look reasonable.

Two issues here: (1) We should get the RA,DEC coordinates for those objects when running with the bailout option, or discard those objects if that's more appropriate. (2) Figure out why these bricks were taking so long to run -- in the Viewer, many of them don't strike me as unusual.

Examples of bricks with zero-d out coordinates: 1854m320, 1851m322.

Examples of bricks that bailed out without that problem, but not obvious why they needed the bailout option: 1851m317, 1854m317.

Attached is a file with a list of these 246 bricks and the following information: filename nbad nbailout ngaia ntot. nbad is the number of sources with RA=0, nbailout is the number of sources with the BAILOUT flag set, ngaia is the number of Gaia stars, ntot is the total number of objects in the brick. dr10bailout.log
