cds-question@unistra.frinfrared-photometrypre-main-sequence-starsyoung-stellar-objectsline-intensitiesspectroscopic-binary-starsmolecular-cloudsWe present 3.6 to 70um Spitzer photometry of 154 weak-line T Tauri stars (WTTSs) in the Chamaeleon, Lupus, Ophiuchus, and Taurus star formation regions, all of which are within 200pc of the Sun. For a comparative study, we also include 33 classical T Tauri stars which are located in the same star-forming regions. Spitzer sensitivities allow us to robustly detect the photosphere in the IRAC bands (3.6 to 8um) and the 24um MIPS band. In the 70um MIPS band, we are able to detect dust emission brighter than roughly 40 times the photosphere. These observations represent the most sensitive WTTSs survey in the mid- to far-infrared to date and reveal the frequency of outer disks (r=3-50AU) around WTTSs. The 70um photometry for half the c2d WTTSs sample (the on-cloud objects), which were not included in the earlier papers in this series, those of Padgett et al. (2006ApJ...645.1283P) and Cieza et al. (2007, Cat. J/ApJ/667/308) are presented here for the first time.2010ApJ...724..835Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/724/835CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJS/196/4 : New young star candidates in Taurus-Auriga (Rebull+, 2011)J/ApJ/712/925 : Transition circumstellar disks in Ophiuchus (Cieza+, 2010)J/A+A/519/A83 : T Tau stars toward the Taurus-Auriga region (Takita+ 2010)J/ApJ/703/1964 : Spectra of three nearby star-forming regions (Furlan+, 2009)J/ApJS/181/321 : Properties of Spitzer c2d dark clouds (Evans+, 2009)J/PASJ/60/209 : Faint companions around YSOs in TMC (Itoh+, 2008)J/ApJ/676/427 : MIPS and IRAC data on ChaII PMS stars (Alcala+, 2008)J/ApJS/177/551 : Spitzer c2d survey of Lupus dark clouds (Merin+, 2008)J/ApJS/179/249 : Low-luminosity embedded protostar population (Dunham+, 2008)J/ApJ/675/1375 : IRAC/MIPS photometry in Cha I (Luhman+, 2008)J/A+A/485/155 : HK photometry of rho Oph PMS stars (Alves de Oliveira+, 2008)J/ApJ/667/308 : Weak-line T Tauri in Spitzer c2d Survey.
