Examples of best-fit SED models using various approaches (see Sect. 5). The top row illustrates MBB models in which the ring radius is a free parameter. In all cases, the disk SEDs were fitted with a single planetesimal ring, as shown in panel a for BD 20-951 and panel b for HD 9672. For disks exhibiting a warm component, an additional BB component (Ring 2) representing warm dust was included in the fit, as demonstrated in panel c for HD 9672 and panel d for HD 39060. The bottom row shows fits using the SD model, where the ring radius is fixed to the value measured from the r²−scaled scattered-light images. If only one ring is resolved, the SED is fitted with a single SD component, as in panel e for HD 112810. For systems with a warm dust component, an additional BB component (Warm Component) was added, as illustrated in panel f for HD 112810. In cases where two cold belts are resolved, the SED is fitted with two SD rings, as shown in panel g for HD 15115 and panel h for HD 131835.
