Few general comments, and I did not read the whole thing.

I think LDM-141 specifies average of 1000 visits per night?

LDM-141 expects false positives to be 50% of real alerts, if the actual number is 400%, do we need to update LDM-141?

Good question, since we are nowhere close to 2:1 real to bogus sources currently. This ratio is over a year old, though, and has not been re-evaluated from ComCam data.

Hmm, with the area so small the distribution across spatial partitions will be very uneven, that will likely cause uneven load across Cassandra cluster.

Yes, this was just for testing. The actual value will be 18000.

Hmm, this depends on nDiaSources being correct and that depends on having DiaSource history.

Yes, this is the one place I currently use the diaSource history. I will attempt to re-write it without needing that history, so that I can skip reading diaSources.

Before many diaObjects were being missed, now they are all correctly loaded
Do not write preloaded diaObjects that were not associated with new diaSources
