NOvA Simulation Request #3061
PhotonTransport attenuation lengths
I added this to the known issues list:
Long attenuation length is set to ~8.5m (based on a benchtop test at Caltech?). Measurements at the module factory seem to favour ~7.5m (eg docdb 8094) (1.5)
I asked Jan to see if he can extract the short length from his data too. Probably we should wait for FD data, but at some point we should probably change these values.
