[Halld-cal] Log book entry with normalization for pi0 calibrations

Dear collaborators,

I have logged two entries containing normalization information for the 
set of runs used for bcal and fcal pi0 calibrations.
https://logbooks.jlab.org/entry/3323867
https://logbooks.jlab.org/entry/3323868

The integrated fluxes do not include corrections for collimation (~0.2) 
or live time (~0.1), which are very large. However, given our best guess 
at these factors, we should be able to estimate the amount of time we 
need to collect a certain amount of statistics during the upcoming run. 
This would be based on the number of pi0s that are found under the pi0 
peaks for the runs specified in the log entry.

We need to have these numbers handy for an update on Monday.

Cheers, Elton.
