There was a problem hiding this comment. this and other methods have a fairly large overlap in implementation. Also, the methods will be easier to use in general if there was only a method accepting the cutEra as a function argument There was a problem hiding this comment. They are prepared for different HI data taking and scenario. We prefer to separate them to make it easy for copy and paste. |

There was a problem hiding this comment. is this commented out code needed? There was a problem hiding this comment. Various HI documents used algo numbers instead of the enum names. We keep it for documentation purpose. |

what about
GenMCcase? It looks liketrackQuality_GenMCreturns some non-false values.Is it intentionally omitted?
