Stars form in the densest, coldest, most quiescent regions of molecular clouds. Molecules provide only probes that can reveal dynamics, physics, chemistry, and evolution these regions, but our understanding inventory sources how this is related to their physical state rudimentary incomplete. The Spectral Legacy Survey (SLS) one seven surveys recently approved by James Clerk Maxwell Telescope (JCMT) Board Directors. Beginning 2007, SLS will produce a spectral imaging survey content distribution all molecules detected 345 GHz atmospheric window (between 332 373 GHz) toward sample five sources. Our intended targets are low‐mass core (NGC 1333 IRAS 4), three high‐mass cores spanning range star‐forming environments evolutionary states (W49, AFGL 2591, 20126), photodissociation region (the Orion Bar). use unique capabilities HARP‐B/ACSIS (Heterodyne Array Receiver Programme B/Auto‐Correlation Spectrometer Imaging System) study structure objects, which span different stages probe during star formation process. As its name suggests, lasting data legacy from JCMT benefit entire astronomical community. such, set (including calibrated cubes, maps emission, line identifications, calculations gas temperature column density) be publicly available.
