Stellar disk sizes in different systems. Comparisons between our estimated R e and l ⋆ and literature measurements; see also Table 6. The left panel compares our measured R e to literature size measurements: the isophotal radius r 25 scaled according to Equation (6) to predict R e, estimates from Salo et al. (2015, “S4G fit”) and Muñoz-Mateos et al. (2015, “S4G profile”), and estimates from 2MASS. The S4G profile−based sizes and 2MASS J-band sizes show good agreement with our estimates. The right panel shows results for our scale length l ⋆ fits. Here, we have only the Salo et al. (2015) literature values to compare to. We do find overall agreement, but see more scatter than for R e.
