Detailed Description

A level-2 "cluster" based trigger.

Jason C. Webb, IUCF

This class implements an L2 gamma, pi0 and electron trigger for both the barrel and endcap calorimeters. The trigger is essentially a "cluster finder". It locates a high tower above a specified threshold, and forms a 3x3 cluster of towers centered on the high tower. If the cluster exceeds a second threshold, the trigger condition is satisfied. An optional "prescaled accept" will accept some prescaled rate of input events.

bool L2gammaAlgo::doEvent ( int  inpEveId,
TrgDataType trgData,
int  emcIn,
unsigned short *  emcData 

process one event through L2 and evaluate. returns true to accept an event, false to reject. fatal algorithm errors will always return true to tick off the shift crew and get them to take action (we hope).

inpEveIdevent id
trgDatathe trigger data block
emcInspecifies whether the calorimeter is in the run or not
emcDatais the L2 data block (raw ADC values) to be processed

Get pointer to block of bytes where L2gammaResult will reside

And write to L2result

Test trig and prescale and fill QA histograms when they are satisfied

int L2gammaAlgo::initRun ( int  run,
int  I_par[5],
float  F_par[5] 

initialize the data structures for the next run

Reset event counters

read in database for this run

determine ideal gains for each of the eta bins

clear high tower and patch thresholds

loop over all db entries and calculate ADC thresholds

I really need to think about this!

second loop over all db entries, this time we calculate ADC thresholds on the 3x3 tower patch

loop over neighboring towers, including the current tower, and add ped/gain to the patch threshold. the result should be sum_i ped_i/g_i for each rdo channel (plus the ET threshold already initialized).

assign this rdo to the physical tower patch

void L2gammaAlgo::printPatchConfig ( int  rdo)
