Code and data for "Response of the near-threshold resonances of the dtμ molecular ion to an effective atomic 2s–2p splitting"

Code and data package accompanying the manuscript "Response of the near-threshold resonances of the dtμ molecular ion to an effective atomic 2s–2p splitting" (submitted to Physical Review A). It contains the Python implementation, frozen basis inputs, archived CAP spectra, validation records, and a step-by-step reproduction guide (REPRODUCE.md). This is the review edition: files are restricted and provided to the editors and referees for the evaluation of the manuscript. An open edition (MIT license for code, CC BY 4.0 for data and documentation) will be released as a new version after publication. The package is split into four parts; see README_FIRST.txt.
