Comparison of the clusters' [Fe/H] (upper panels) and distance (lower panels) values derived from their RRab stars and their values from the literature. Clusters in the VIVACE, Z24, and Gaia samples are shown in the left, center, and right panels, respectively. The black dotted lines show the zero functions, while the median and MAD of the y-axis values in each panel are highlighted in blue text and as a blue line and shaded region, respectively. The y-axis error bars shown in the upper panels correspond to the errors in our [Fe/H] estimates, while the y-axis error bars in the lower panels correspond to the errors in the RRab-based distances divided by the nominal values from the literature. Clusters with relative distance differences greater than 10% have their names highlighted in the lower panels.
