Detailed Description

RAWDataHeaderV5 In version 5, the RDH stores the information of the heartbeat trigger which opens the page. Additional detector specific triggers can be in the payload.

preliminary description of the fields can be found here https://gitlab.cern.ch/AliceO2Group/wp6-doc/blob/master/rdh/RDHV5.md accessed on Oct 07 2019 FIXME: replace citation with correct ALICE note reference when published
