MOPAC7 MINDO/3 parameter-data provenance
=========================================

xndo-rs 0.2.3 retains a consolidated machine-readable MINDO/3 atomic and
atom-pair parameter table cross-checked against the public-domain MOPAC7 source.

Upstream source mirror:
  https://sources.debian.org/src/mopac7/1.15-4/fortran/block.f/
Public-domain status is stated in the MOPAC7 program source and in the MOPAC7
project distribution metadata.

The xndo-rs tables are:
  src/data/mindo3_parameters.csv
  src/data/mindo3_pair_parameters.csv

The atom-pair table follows MOPAC7 BETA3/ALP3 bond-type indices. In particular,
P-Cl, S-Cl and Cl-Cl correspond to the distinct tail entries 151, 152 and 153.
