 I then did counts to find out how many have x detections or x stackdetections (up to 20 in both). For easy comparisons, I show both tables side by side (they are not related):

   * yes we do: this happened on a full batch, 12884 - all detections were basically null, except for the ramean/decmean.  This was at ra = 0 dec = -33.
   * Is it PSPS or IPPTOPSPS's fault? I downloaded 12884's batch and investigated, it looks like we shipped them 0's.
   * Is it IPPTOPSPS or DVO's fault?  Where are the 0's? This is stage_id 121470, which translates to region s3000/6992.13.  This is located here:  /data/stsci00.0/eugene/lap.pv2.20141215/catdir.01/s3000/6992.13* . I opened the files in topcat, and there are 0's, so ipptopsps did the correct thing, but the dvo was incorrect.

   * yes : can I do a query of select batchid, count_big(*) from ObjectThin where nstackdetections = 0 and ndetections = 0 group by batchid --> into query called 'funkybatches'
