Table 1: Table of observed and calculated properties of select systems.

We list the properties of the observed white dwarf systems hosting dusty debris disks, along with our computed sublimation radii within those systems for various planetary materials and rigid-body Roche limits for typical endmember planetesimal densities. The observed locations of the disks are in alignment with the calculated sublimation radii (inner disk edge) and Roche radii (outer disk edge).
