BANYAN Σ kinematic-model diagnostic figures for MOCAdb

This dataset contains 10,049 publicly releasable PNG diagnostic figures produced for the BANYAN Σ spatial-kinematic models associated with the Montreal Open Clusters and Associations Database (MOCAdb). Each file is named using its MOCAdb association identifier and shows projections of association members and their uncertainties in Galactic XYZ positions and UVW velocities, together with fitted Gaussian-mixture model components. The release excludes all RHEA-prefixed figures and every association whose current moca_associations.is_public flag was 0. The figures accompany Section V.3 and Figure 16 of Gagné et al. (2026), accepted in the Astrophysical Journal Supplement Series. The files are divided into ZIP archives for reliable transfer; manifest.csv maps every figure to its archive and records its size, dimensions, and SHA-256 checksum.
