Mean Cal‐PSWDB colors for sources in the sample with ﹩\left|b\right|> 20^{\circ }﹩. Data are shown in brown, and error bars are suppressed. An ﹩A_{v}=1﹩ interstellar reddening vector is shown in red. Source density contours of 12%, 40%, 70%, 80%, and 90% of the maximum source density are shown in black. The line at ﹩H-K_{s}=0.2﹩ illustrates the PSC color selection criteria. The Cal‐PSWDB colors for many sources fall outside the PSC color selection criteria because of the larger errors in PSC photometry.
