This archive contains bootstrap samples of single-hadron masses and finite-volume nucleon-pion energies used in https://arxiv.org/pdf/2208.03867. Each (ASCII) file contains 802 lines in the following format: 801 1 0 0 1 #Header line. 0 <mean> #the energy evaluated on the mean 0 <bsample 1> #first boostrap sample .... 0 <bsample 800> #800th boostrap sample The directory structure and file names are as follows. single_hadrons/m_<hadron>_smpls.dat where <hadron> = pion or nucleon, contains the single-hadron masses. The I=1/2 and I=3/2 spectra are located in the directories 'isodoublet_nonstrange' and 'isoquartet_nonstrange_fermionic', respectively. Each subdirectory contains a single irrep and is denoted "dsq<mom>_<irrep>" and contains files level_<n>_ecm_over_m_smpls.dat for each level. The energies given in these files are normailzed by mpi and are in the center-of-momentum frame.
