User story: While processing DC2.1 data we found many instances of the astrometry matcher failing.

In previous data challenges, the pessimisticB matcher was more robust to failures, so this error is confusing.    I am in the process of copying a problematic visit over to lsst-dev at /scratch/<USER>Run2.1i/w_2019_17.  This visit had failures for detectors: 78, 81, 85, 89, 135, 139, 150, 181, 185.
