Detailed Description

Unpacks "SlowData" packages used for SiPM calibration and other purposes in HCAL Local DAQ.

  To use this code in an analysis module, you need only:

  analyze(const edm::Event& iEvent, const edm::EventSetup&) {

  edm::Handle<edm::FEDRawDataCollection> rawraw;  
  iEvent.getByType(rawraw);        

  hcaltb::HcalTBSlowDataUnpacker sdp;
  std::map<std::string,std::string> strings;
  std::map<std::string,double> numerics;

if regular slow data sdp.unpackMaps(rawraw->FEDData(hcaltb::HcalTBSlowDataUnpacker::STANDARD_FED_ID),strings,numerics); if SiPM Cal slow data (different 'FED') sdp.unpackMaps(rawraw->FEDData(hcaltb::HcalTBSlowDataUnpacker::SIPM_CAL_FED_ID),strings,numerics);
