// *********************************
// MINERvA CC1pi+/- signal definition (2015 release)
// Note: There is a 2016 release which is different to this (listed below), but
// it is CCNpi+ and has a different W cut
// Note2: The W cut is implemented in the class implementation in MINERvA/
// rather than here so we can draw events that don't pass the W cut (W cut is
// 1.4 GeV)
// Could possibly be changed for slight speed increase since less events
// would be used
//
// MINERvA signal is slightly different to MiniBooNE
//
// Exactly one negative muon
// Exactly one charged pion (both + and -); however, there is a Michel e-
// requirement but UNCLEAR IF UNFOLDED OR NOT (so don't know if should be
// applied)
// Exactly 1 charged pion exits (so + and - charge), however, has Michel
// electron requirement, so look for + only here?
// No restriction on neutral pions or other mesons
// MINERvA has unfolded and not unfolded muon phase space for 2015
//
// Possible issues with the data:
// 1) pi- is allowed in signal even when Michel cut included; most pi- is efficiency corrected in GENIE
// 2) There is a T_pi < 350 MeV cut coming from requiring a stopping pion; this is efficiency corrected in GENIE
// 3) There is a 1.5 < Enu < 10.0 cut in signal definition
// 4) There is an angular muon cut which is sometimes efficiency corrected (why we have bool isRestricted below)
//
// Nice things:
// Much data given: with and without muon angle cuts and with and without shape
// only data + covariance
//
