DESCRIPTION:ALMA line surveys offer a unique opportunity to study large po
 pulations of protoplanetary disks with low integration times per source. H
 owever\, classic image-plane analyses are limited in their ability to accu
 rately extract bulk gas disk properties (i.e. sizes and fluxes) from the r
 esulting moderate angular resolution data. In this talk\, I present measur
 ements of key disk properties inferred from parametric modeling of ALMA Ba
 nd 7 12CO (J=3-2) spectral line visibilities. From these models\, I derive
  gas-disk radii\, integrated fluxes\, optically thick emission layers\, an
 d brightness temperature profiles for the disk population in the old (4–
 14 Myr) Upper Scorpius star-forming region\, using moderate angular resolu
 tion observations (0.1–0.3″). Furthermore\, I show how disk-based stel
 lar mass estimates can be used to benchmark pre-main-sequence evolutionary
  tracks.
