[Halld-offline] Offline Software Meeting Minutes, April 29, 2015

[Sean Dobbs]

Hi Richard,

Are you using the latest version of the CCDB constants? I updated the
rf_period yesterday based on the results of a meeting Paul Mattione had on
the MO.

I see the following results:

farm1401> ccdb dump /PHOTON_BEAM/RF/rf_period:2933
#Spring running is at ~2ns period
2.004008

>From HDGeant:  (Run 2933)

 settofg: beam_bucket_period_ns set to    2.0040081
