    5 Comments: some experiment determined fluxes purely by simulating the beamline, others fitted selected events (often CCQE) to get a sufficient interaction model description and then used that to go to a flux. In the best cases, these two methods are compared and the differences is an estimate of the flux error. This was not always the case though and the neutrino fluxes should always be taken with a pinch of salt!
     5'''Comments:''' some experiments determined fluxes solely by simulating the beamline and target interaction; others added muon monitors to provide additional flux information; others fitted selected events (often CCQE) and then used that to go to a flux, sometimes without providing information on how accurate the simulation was. In the best cases, all these methods are combined and compared and the differences is an estimate of the flux error. This was not always the case though and the neutrino fluxes should always be taken with a pinch of salt.

    7 '''Beware of experiments using these sorts of methods.''' In correcting the CC1pi+ cross-section by using the CC1pi+/CCQE ratio by multiplying it by the CCQE cross-section, Wilkinson and Rodrigues found that the BNL total cross-section correction was large (arxiv:1411.4482v1) compared to ANL. This may be a result of how their flux was estimated.
     7'''Beware of experiments using only CCQE events to estimate the neutrino flux''' In correcting the CC1pi+ cross-section by using the CC1pi+/CCQE ratio by multiplying it by the CCQE cross-section, Wilkinson and Rodrigues found that the BNL total cross-section correction was large (arxiv:1411.4482v1) compared to ANL. BNL used a fit to CCQE events to estimate their flux, which assumes a understood CCQE interaction model and an understanding of deuterium effects.
