CMZoom II: Catalog of Compact Submillimeter Dust Continuum Sources in
  the Milky Way's Central Molecular Zone
  In this paper we present the CMZoom Survey's catalog of compact sources (<
10'', ~0.4pc) within the Central Molecular Zone (CMZ). CMZoom is a
Submillimeter Array (SMA) large program designed to provide a complete and
unbiased map of all high column density gas (N(H$_2$) $\geq$ 10$^{23}$
cm$^{-2}$) of the innermost 500pc of the Galaxy in the 1.3mm dust continuum. We
generate both a robust catalog designed to reduce spurious source detections,
and a second catalog with higher completeness, both generated using a pruned
dendrogram. In the robust catalog, we report 285 compact sources, or 816 in the
high completeness catalog. These sources have effective radii between 0.04-0.4
pc, and are the potential progenitors of star clusters. The masses for both
catalogs are dominated by the Sagittarius B2 cloud complex, where masses are
likely unreliable due to free-free contamination, uncertain dust temperatures,
and line-of-sight confusion. Given the survey selection and completeness, we
predict that our robust catalog accounts for more than ~99% of compact
substructure capable of forming high mass stars in the CMZ. This catalog
provides a crucial foundation for future studies of high-mass star formation in
the Milky Way's Galactic Center.
