Data Release: Measurement of neutron production in atmospheric neutrino interactions at Super-Kamiokande

This data release accompanies the article "Measurement of neutron production in atmospheric neutrino interactions at Super-Kamiokande". The data provided here includes observed average neutron multiplicity in atmospheric neutrino interactions at Super-Kamiokande (SK) as a function of the event's visible energy, along with model predictions using various combinations of final-state interaction (FSI) models and secondary hadron interaction models.

For details on the data selection and compared models, please refer to the associated article on arXiv.

Files Included:

1. x_bin_edges.txt:Contains the x bin edges for all data, formatted as a list, which is equivalent to np.logspace(np.log10(30), 4, 51) in numpy. The bin edges are common for all event types included in the two comma-delimited csv files below.

2. data_observations.csv:Contains the observed SK data.  - event_type: (all, sr, mr)    - all: All events that pass the selection criteria.    - sr: Single-ring events only.    - mr: Multi-ring events only.  - x_bin_id: Bin ID to match between data observations and model predictions.  - x_bin_center: Mean value of visible energy for events in the x bin.  - y_nmult_est: Average estimated neutron multiplicity for events in the x bin.

Data includes estimated y errors:  - yerr_total: Total uncertainty for the observed y_nmult_est, calculated as the L2 norm of the following …
