Abstract:
I present a catalog of point-source objects toward NGC 1333, resolving
a wide variety of confusion about source names (and occasionally
positions) in the literature. I incorporate data from optical to radio
wavelengths, but focus most of the effort on being complete and
accurate from J (1.25µm) to 24µm. The catalog encompasses
52°<R.A.<52.5° and 31°<decl.<31.6°.
Cross-identifications include those from more than 25 papers and
catalogs from 1994 to 2014, primarily those in wide use as origins of
nomenclature. Gaps in our knowledge are identified, with the most
important being a lack of spectroscopy for spectral types or even
confirmation of youth and/or cluster membership. I fit a slope to the
spectral energy distribution (SED) between 2 and 24µm for the
members (and candidate members) to obtain an SED classification, and I
compare the resulting classes to those for the same sources in the
literature, and for an SED fit between 2 and 8µm. While there are
certainly differences, for the majority of the sources, there is good
agreement.
Description:
I present a catalog of point-source objects toward NGC 1333. I
incorporated data from optical to radio wavelengths, but focused most
of my effort on J (1.25µm) to 24µm. Cross-identifications
include those from more than 25 papers and catalogs from 1994 to 2015
(see Table 1). In the process of assembling the literature catalog of
sources, I reconciled many ambiguities and inconsistencies in the
literature. All of the reconciled cross-identifications in NGC 1333
are included in Table2, including an indication of whether or not the
corresponding survey identified the object as a Young Stellar Object
(YSO).
All of the aggregate J-[24] single-epoch photometry appears in Table3.
There are nearly 7000 objects in the catalog, about 300 of which are
identified in the literature as YSO candidates.

Note (1): Reference codes are defined as follows:
ASR = Aspin et al. 1994 (cat. J/A+AS/106/165);
Aspin03 = Aspin (2003AJ....125.1480A 2003AJ....125.1480A);

Wilking04 = Wilking et al. 2004 (cat. J/AJ/127/1131);
Winston10 = Winston et al. 2010 (cat. J/AJ/140/266).
Note (2): If YSO candidate. In the spirit of Wilking et al.
(2001ApJ...551..357W 2001ApJ...551..357W), I define the NIR to MIR (2-24µm) slope of the
SED, α=d(logλFλ)/d(logλ).
Note (3): Our SED classification scheme is defined as:
I = YSO candidate with α>0.3;
flat = YSO candidate with -0.3<α<0.3 (flat spectrum)
II = YSO candidate with -1.6<α< -0.3;
III = YSO candidate with α< -1.6.
notY = not an YSO candidate
Note that there are 25 objects with insufficient points in the Spectral
Energy Distribution (SED), such that I cannot assign a class.
Note (4): Table6 has the numbers of objects in my catalog for which my classes
match (or do not match) the classes obtained from this other approach.
Note (5): Arnold et al. (2012ApJS..201...12A 2012ApJS..201...12A) have different classes than I
have defined:
FS = Flat-spectrum source;
TD = Transition Disk class;
PTD = Pre-Transition Disk class.
Table6 has the numbers of objects in my catalog for which my classes match
(or do not match) the classes obtained from this other approach.
Note (6): For the most embedded sources, there is no provision in our scheme for
identifying Class 0, and I do not use points at wavelengths longer than
24µm to determine classes. I would expect, though, that those objects
that others have identified as Class 0 would work out to be Class I in my
scheme. Please refer to Section 5 in the paper for additional details.

Global notes:
Note (G1): IAU standards recommend not renaming previously identified sources,
but as one of the purposes of the present catalog is to sort out
inconsistencies and inaccuracies in existing catalogs, assigning a new,
coordinate-based name seems appropriate. The coordinate-based names
presented here (in Tables 2 and 3) should be preceded by "R15-NGC 1333."
