Abstract:
We present the results of an extensive near-infrared (JHK) imaging
survey of the NGC 1333 star forming region. Our survey covers an area
more than 4 times larger than the previous imaging survey of this
cloud reported by Aspin et al. (1994, Cat. J/A+AS/106/165) and is
sufficiently sensitive to render an accurate census of the embedded
stellar population in the cloud. We detected 275 sources with
mK<14.5mag within the 432 square arcminute region surveyed.
Description:
The near-infrared imaging observations reported were obtained using
the National Optical Astronomy Observatory (NOAO) Simultaneous Quad
Infrared Imaging Device (QSIID) on the Kitt Peak National Observatory
(KPNO) 1.3m telescope in 1994 October.
