Query: Statistical Properties of Galactic {\delta} Scuti Stars: Revisited   We present statistical characteristics of 1,578 {\delta} Scuti stars
including nearby field stars and cluster member stars within the Milky Way. We
obtained 46% of these stars (718 stars) from the works done by Rodr\'{i}guez
and collected the remaining 54% stars (860 stars) from other literatures. We
updated the entries with the latest information of sky coordinate, color,
rotational velocity, spectral type, period, amplitude and binarity. The
majority of our sample are well characterized in terms of typical period range
(0.02-0.25 days), pulsation amplitudes (<0.5 mag) and spectral types (A-F
type). Given this list of {\delta} Scuti stars, we examined relations between
their physical properties (i.e., periods, amplitudes, spectral types and
rotational velocities) for field stars and cluster members, and confirmed that
the correlations of properties are not significantly different from those
reported in the Rodr\'{i}guez's works. All the {\delta} Scuti stars are
cross-matched with several X-ray and UV catalogs, resulting in 27 X-ray and 41
UV-only counterparts. These counterparts are interesting targets for further
study because of their rarity and uniqueness in showing {\delta} Scuti-type
variability and X-ray/UV emission at the same time. The compiled catalog can be
accessed through the web interface http://stardb.yonsei.ac.kr/DeltaScuti
