Abstract:
We present near-IR (NIR) J, H and K mosaic images of the active star
forming region associated with the optical reflection nebula NGC 1333.
These observations cover an area of 10'x10' and are centered on the
energetic outflow source SSV 13. From these data, we have obtained NIR
photometry of 134 objects down to a 5σ limiting K magnitude of
mK=16.2 and a conservative survey completeness limit of mK=16.0. With
the addition of new optical R and I band CCD photometry, and both
(sub)mm line and continuum maps, we analyse and discuss the region's
morphology and spatial source distribution with additional reference
to existing multi-wavelength data.

Note (1): CA = close-Above the upper reddening vector
CB = close-Below the lower reddening vector
Note (2): In the mK-MK column, where a range of values are given e.g. 15.8-10.8,
this refers to the range of valid distance moduli when that could be
possible given an implied spectral type range (e.g. B8-O5 V) estimated
from analysing likely errors on the photometry. Such errors could move
the location of the CA and CB stars between the two reddening vectors
to a certain maximum extent. This maximum gives the limit of the
spectral type range.
Note (3): NEB = nebulosity, no apparent star
Note (4): The following symbols are used:
* = implied from m-M > 13.9 ≡ 6kpc
a = same as * but using assumed Spectral Type
- = m-M < 7.7 + implied AV>5
+ = implied from associated Halpha emission
o = implied from optical c-c diagram
