A Catalog of Point Sources Towards NGC 1333

TL;DR

This paper compiles a comprehensive catalog of point sources in NGC 1333 across multiple wavelengths, clarifying previous ambiguities and providing spectral energy distribution classifications, but lacking spectroscopic confirmation.

Contribution

It offers an updated, cross-referenced catalog of sources in NGC 1333 with improved positional accuracy and SED-based classifications, addressing gaps in spectral data.

Findings

Catalog includes 52 deg<RA<52.5 deg and 31 deg<Dec<31.6 deg.

Good agreement between SED classifications and literature for most sources.

Identifies gaps such as lack of spectroscopic data for many sources.

Abstract

I present a catalog of point source objects towards 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 (1.25 um) to 24 um. The catalog encompasses 52 deg<RA<52.5 deg and 31 deg<Dec<31.6 deg. Cross-identifications include those from more than 25 papers and catalogs from 1994-2014, 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 24 um for the members (and candidate members) to obtain an SED classification, and compare the resulting classes to those for the same sources in the literature, and for an SED fit between 2 and 8 um. While there are certainly differences, for the majority of the sources, there is good agreement.
