Query: Mass Assembly of Stellar Systems and their Evolution with the SMA
  (MASSES) -- Full Data Release   We present and release the full dataset for the Mass Assembly of Stellar
Systems and their Evolution with the SMA (MASSES) survey. This survey used the
Submillimeter Array (SMA) to image the 74 known protostars within the Perseus
molecular cloud. The SMA was used in two array configurations to capture
outflows for scales $>$30$^{\prime\prime}$ ($>$9000 au) and to probe scales
down to $\sim$1$^{\prime\prime}$ ($\sim$300 au). The protostars were observed
with the 1.3 mm and 850 $\mu$m receivers simultaneously to detect continuum at
both wavelengths and molecular line emission from CO(2-1), $^{13}$CO(2-1),
C$^{18}$O(2-1), N$_2$D$^+$(3-2), CO(3-2), HCO$^+$(4-3), and
H$^{13}$CO$^+$(4-3). Some of the observations also used the SMA's recently
upgraded correlator, SWARM, whose broader bandwidth allowed for several more
spectral lines to be observed (e.g., SO, H$_2$CO, DCO$^+$, DCN, CS, CN). Of the
main continuum and spectral tracers observed, 84% of the images and cubes had
emission detected. The median C$^{18}$O(2-1) linewidth is $\sim$1.0 km
s$^{-1}$, which is slightly higher than those measured with single-dish
telescopes at scales of 3000-20000 au. Of the 74 targets, six are suggested to
be first hydrostatic core candidates, and we suggest that L1451-mm is the best
candidate. We question a previous continuum detection toward L1448 IRS2E. In
the SVS13 system, SVS13A certainly appears to be the most evolved source, while
SVS13C appears to be hotter and more evolved than SVS13B. The MASSES survey is
the largest publicly available interferometric continuum and spectral line
protostellar survey to date, and is largely unbiased as it only targets
protostars in Perseus. All visibility ($uv$) data and imaged data are publicly
available at https://dataverse.harvard.edu/dataverse/full_MASSES/.
