they got 3-4 exposures, which all were >0.4 survey speed, and overall high efftime_spec.
but their lrg success rate is lower than nominal.
here s the per-petal lrg success rate nightqa plot:
here s the sky map, with the grey shaded area showing 50 deg from the Moon:
and here are some stats for the five dark tiles observed that night, where one can see that tileids=4014 and 11707 are the dubious ones:
# TILEID NEXP EFFTIME_SPEC NGOOD_LRG/NLRG=GOOD_FRAC
8084 1 1103 637/649=0.98
6226 3 1295 330/339=0.97
5841 3 1421 309/315=0.98
4014 4 1506 635/665=0.95 # <- in des region, at dec~-17
11707 3 1314 823/905=0.91 # <- north of the ngc region
I guess we d want to mark those exposures as "bad" and reprocess?
