    Specifications Table . Experimental design, materials and methods Measurements were taken by a special team of 2 trained assistants, while other information was taken from the RLMS survey which contains questions regarding an individual׳s socioeconomic characteristics and family background [1]. The data were anonymized before being provided to the authors for statistical analysis. The finger measurements were taken using electronic calipers. Actual measurements were made from the palmar digital crease to the fingertip of the index and ring fingers. Then measurements were rounded to the nearest millimeter.
    Data These data include a map showing the location of Holtun in Guatemala and its relation to neighboring sites (Fig. 1), maps of the site showing the location of groups cited in this CA-074 Me study (Fig. 2), maps of the locations of excavation units within the patios where samples were found (Figs. 3 and 5), profiles of excavations showing stratigraphy of excavation units where samples were found (Figs. 4 and 6), photographs of sherds and an atlas of paste fabrics with corresponding table of type: varieties (Appendix A), and compositional data produced by Neutron Activation Analysis (NAA) at the Research Reactor, University of Missouri (MURR). The NAA data include a table of Mahalonobis distance calculations of elemental concentrations between samples (Table 1), a chart and table of canonical discriminant analyses of paste groups and elemental concentrations (Fig. 7 and Table 2), and a chart of a log-based Euclidian distance search between the samples (Fig. 8). The data also include results of Chi-Square tests of association between paste chemical composition groups and ceramic attributes including type: variety, group, ware, temper, decoration, and form (Appendix B).
