      Description

      There are still some pixels with negative variance in the calexps. While investigating DM-31695, I found some cases with single pixels or small areas of negative variance. Here are some examples:

      detector: 57, visit: 23872

      detector: 77, visit: 28976

      detector: 93, visit: 23912

      detector: 70, visit: 23900
