Excited-state uncertainties in lattice-QCD calculations of multi-hadron systems

Data for the NPLQCD collaboration project on "Excited-state uncertainties in lattice-QCD calculations of multi-hadron systems" (https://arxiv.org/pdf/2601.22272,https://arxiv.org/pdf/2601.22273). Data sets are in HDF5 format for pion (B0_A1u_b,f), nucleon (B1_G1_b,f) and isospin I=0 (B2_I0_T1_b,f) and I=1 (B2,I1_A1_b,f) two-nucleon channels. The data structure for the full data set is {N_cfg, N, 1, N, 1 Nt} where N is the number of operators in a given channel, N_cfg=16,368 and Nt=24 is the temporal extent. The second data set is averaged over configurations down to N_blk=327 blocks. The labels "_b,f" correspond to propagation forward and backward in time.
