Latest keep-ups without POT information
I was working with the latest reco keep-ups (S15-07-30) when I discovered that the information on the total POT seems to be missing for these files (both for the ND and the FD). Does anyone know what might be the reason? Most of these files date back to June, when the beam was definitely ON (actually, at the highest power).
I created definitions to access these files easily:
The request ticket related to this reco keep-up is RITM0251145.

Nothing actually went wrong here, the spills just fail the good spill cut. Most of the dataset was recorded with the beam off, but the runs that had beam had the horn off, so they fail the good spill cut. Bad spills aren't included in the CAF TotalPOT histogram, but you can see them in the spill tree.

I checked the logs of the reconstruction keep-up (S15-07-30).
There is any error.
There are printouts like
POT in subrun ## = 0
where ## is the subrun number.
Checking the artdaq metadata there is some file with
online.totalevents: is > 100 for almost all files, however it is always > 0
As Dominick pointed out, looks like this issue is due to run conditions and not to data processing.
There is something else that could be check?
