SEDs with stellar atmosphere and disk models for log(L*/Lsol)≤ − 1.8. In each panel, the blue open and filled circles show the observed and dereddened data, respectively. The grey solid line shows the SED of the stellar atmosphere model (Allard et al. 2001; Hauschildt et al. 1999). The stellar atmospheres shown here have the values of Teff and log(g) listed in Table 6, and are superposed (not fit) onto the data for the cloud distances listed in Table 2. The black solid line is the predicted SED of a face-on, flared disk with an inner radius equal to the stellar radius (Ri = R*). The black dashed line is the predicted SED of a face-on, flat disk with Ri = R*. The green line denotes the best fit to the data and is solid for flared disk models and dashed for flat disk models, as listed in Table 6. Source #11 is best-fit by a flat, face-on disk with Ri = R*. Increased inner radii are required for #1 (Ri = 4 R*) and #13 (Ri = 3 R*). Inclined disks with Ri = R* are required for #5, #7, and #18 (i = 60°). Inclined disk (i = 60°) with large inner radii (Ri = 3 R*) are required for #14 and #17.
