J/ApJ/655/958     90-GHz observations in NGC 1333           (Walsh+, 2007)

A large-scale survey of NGC 1333. Walsh A.J., Myers P.C., Di Francesco J., Mohanty S., Bourke T.L., Gutermuth R., Wilner D. <Astrophys. J., 655, 958-972 (2007)> =2007ApJ...655..958W

The N2H+ emission follows very closely the submillimeter dust continuum emission, while HCO+ emission appears more spatially extended and also traces outflows. We have identified 93 N2H+ cores using the CLUMPFIND algorithm, and we derive N2H+ core masses between 0.05 and 2.5M , with uncertainties of a factor of a few, dominated by the adopted N2H+ abundance. Description: Observations of NGC 1333 were made with the 10-element Berkeley Illinois Maryland Association (BIMA) interferometer, at Hat Creek, CA, operating simultaneously at 89 and 93GHz. The field was divided into two halves, with the southern half observed mostly in the fall of 2001, and the northern half observed in the spring of 2002. File Summary:
