Three are in Taurus and four in the TW Hydrae Association (TWA), and all are classical T Tauri (cTT) analogs. We detect two of the three Taurus disks (one only marginally), but none of the TWA ones. For standard grains in cTT disks, our 3{sigma} limits correspond to a dust mass of 1.2M_{Earth}_ in Taurus and a mere 0.2M_{Earth}_ in the TWA (3-10x deeper than previous work). We combine our data with other submillimeter/millimeter (sub-mm/mm) surveys of Taurus, {rho} Oph, and the TWA to investigate the trends in disk mass and grain growth during the cTT phase.2013ApJ...773..168Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/773/168CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/771/129 : Submillimetric Class II sources of Taurus (Andrews+, 2013)J/ApJ/751/115 : Millimeter emission from Taurus binary systems (Harris+, 2012)J/ApJ/731/8 : Multiple star formation in Taurus-Auriga (Kraus+, 2011)J/A+A/515/A75 : Low-mass stars in {rho} Oph cloud (Alves de Oliveira+, 2010)J/ApJ/720/480 : DISCS.
