RatesAnalysis: Read express stream prescale from input file
Read the express stream prescales from the input AOD file.
Example: (based on results of test_trigP1_v1PhysP1_T0MonTrf_build test on r24 nightly)
| chain | base rate [Hz] | express rate [Hz] | prescale | express prescale |
|---|---|---|---|---|
| HLT_mb_sp_L1RD0_FILLED | 730336.4696 | 73033.6470 | 10 | 100 |
in rates express prescale (for that chain) = prescale (10) * express prescale (10)
