Abstract:
The Differential Speckle Survey Instrument (DSSI) was relocated to the
Astrophysical Research Consortium 3.5m telescope at Apache Point
Observatory (APO) in early 2022. Here we present results from the
first year of observations along with an updated instrument
description for DSSI at APO, including a detailed description of a new
internal slit mask assembly used to measure the instrument plate scale
from first principles. Astrometric precision for DSSI at APO during
this time was measured to be 2.06±0.11mas, with a photometric
precision of 0.14±0.04mag. Results of 40 resolved binary systems
are reported, including two that were previously unknown to be
binaries: HIP7535 and HIP9603. We also present updated orbital fits
for two systems: HIP93903 and HIP100714. Finally, we report updated or
confirmed dispositions for five Kepler Objects of Interest (KOIs) that
were previously explored in Colton et al., using speckle imaging to
discern common proper motions pairs from line of sight companions:
KOI-270, KOI-959, KOI-1613, KOI-1962, and KOI-3214AB.
Description:
A description of the APO on ACR 3.5m telescope instrument is available
in section 2 of the article.

Interferometric Catalog;
