Detailed Description

This edm source module generates Ecal Digis (data frames and TPGs) according to a given pattern. The pattern is defined as function of event id, crystal/TT, and time sample. Only barrel is currently supported for the crystal channel data.

Module parameters (in addition to standard source parameters):

• string formula: formula of crystal channel time sample encoded ADC counts.
• string tpFormula: formula of trigger primitives.
• untracked bool verbose: verbosity switch

The crystal ADC formula is parametrized with the following variables:

• ieta0: crystal eta index starting from 0 at eta- end of barrel
• iphi0: crystal phi index starting at Phi=0deg. in std CMS coordinates
• ievt0 event sequence number within the job run starting from 0
• isample0 sample time position starting from 0

The trigger primitive formula is parametrized with the following variables:

• ieta0: trigger tower eta index starting from 0 at eta- end of barrel
• iphi0: trigger tower index starting at Phi=0deg. in std CMS coordinates
• ievt0 event sequence number within the job run starting from 0
• isample0 sample time position starting from 0

In both formulae 'itt0' shortcut can be used for the trigger tower index within the SM starting at 0 from lowest relative eta and lowest phi and increasing first with phi then with eta. The syntax for the formula is the syntax defined in ROOT TFormula
