Stellar mass-to-light ratios in the I band (open circles) and [3.6] (filled circles) as in Figure 3 corrected with V − I as a second color term as per Table 6. Though the typical correction is less than 0.1 dex, the reduction in scatter is noticeable. The data are re-fit (solid lines) to provide an improved CMLR (Table 7). The previous fits from Figure 3 (dashed lines) are reproduced as here for comparison.
