The COMPLETE Survey will produce an unbiased database that will serve the star-formation research community for many years to come. COMPLETE is comprised of the CoOrdinated Molecular Probe Line, Extinction and Thermal Emission observations of a small set of large star-forming regions scheduled to be extensively observed as part of the SIRTF c2d Legacy Program. COMPLETE is unique in its coordinated approach - prior observations of the types included in COMPLETE abound, but they only rarely fully sample any region, and no survey has ever covered a single ( ˜10 pc) region fully with molecular-line, extinction and dust-emission observations. COMPLETE will provide star-formation theories with statistical constraints on the temporal and spatial frequency of inward motions, outflow, cloud disruption, core formation and other key parameters.
Here we present a summary of results from the first year of COMPLETE observations and analysis: maps of 12CO and 13CO J = 1--0 emission in Perseus, from the 32-element SEQUOIA array of the Five College Radio Astronomy Observatory (FCRAO); 850μ m thermal continuum emission in Ophiuchus from SCUBA on JCMT; Dust column density maps of Perseus and Ophiuchus from a reanalysis of ISSA.
In particular we show that the column density derived from 100μ m emission is not a good tracer of large-scale extinction in regions of active star-formation.
