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);
