Gaia--HST validation atlas for globular-cluster proper-motion dispersion profiles

This release provides the Acta Astronomica submission-oriented v1.1.0 package for the Gaia--HST validation atlas of globular-cluster proper-motion dispersion profiles. The package contains matched-bin Gaia--HST validation products, the cluster-level validation atlas, robustness summaries, metadata, checksums, source-code support files and manuscript-support materials. The validation sample contains 680 matched Gaia--HST radial bins for 56 overlap globular clusters. The cluster-level readiness classes are A=38, B=8, C=8, D=2 and E=0. This release updates the archive framing, metadata and manuscript-support files for the Acta Astronomica version of the paper. The numerical matched-bin products and cluster-level validation results are retained as the reproducible basis for the reported statistics.
