Comparison of the values of stellar temperature (top left), disk accretion rate (top right), and disk mass (bottom left and right) found from SED fitting with values quoted in the literature and derived from different methods. The dashed line shows where the values would be equal, and the gray area shows where the agreement is better than ±0.2 orders of magnitude for the temperature, and ±1 order of magnitude for the disk mass and accretion rate. Error bars in the y‐direction indicate the range of values of the models shown in Fig. 1. Error bars in the x‐direction show the range between the lowest value and the highest value quoted in the literature. For the stellar temperature, only one reference (Kenyon & Hartmann 1995) was used, and therefore no uncertainties are shown on the x‐axis. The likely uncertainty quoted by the authors is ±1 spectral class, corresponding roughly to ±100 K.
