Query: The FourStar Galaxy Evolution Survey (ZFOURGE): ultraviolet to
  far-infrared catalogs, medium-bandwidth photometric redshifts with improved
  accuracy, stellar masses, and confirmation of quiescent galaxies to z~3.5   The FourStar galaxy evolution survey (ZFOURGE) is a 45 night legacy program
with the FourStar near-infrared camera on Magellan and one of the most
sensitive surveys to date. ZFOURGE covers a total of $400\ \mathrm{arcmin}^2$
in cosmic fields CDFS, COSMOS and UDS, overlapping CANDELS. We present
photometric catalogs comprising $>70,000$ galaxies, selected from ultradeep
$K_s$-band detection images ($25.5-26.5$ AB mag, $5\sigma$, total), and $>80\%$
complete to $K_s<25.3-25.9$ AB. We use 5 near-IR medium-bandwidth filters
($J_1,J_2,J_3,H_s,H_l$) as well as broad-band $K_s$ at $1.05\ - 2.16\ \mu m$ to
$25-26$ AB at a seeing of $\sim0.5$". Each field has ancillary imaging in
$26-40$ filters at $0.3-8\ \mu m$. We derive photometric redshifts and stellar
population properties. Comparing with spectroscopic redshifts indicates a
photometric redshift uncertainty $\sigma_z={0.010,0.009}$, and 0.011 in CDFS,
COSMOS, and UDS. As spectroscopic samples are often biased towards bright and
blue sources, we also inspect the photometric redshift differences between
close pairs of galaxies, finding $\sigma_{z,pairs}= 0.01-0.02$ at $1<z<2.5$. We
quantify how $\sigma_{z,pairs}$ depends on redshift, magnitude, SED type, and
the inclusion of FourStar medium bands. $\sigma_{z,pairs}$ is smallest for
bright, blue star-forming samples, while red star-forming galaxies have the
worst $\sigma_{z,pairs}$. Including FourStar medium bands reduces
$\sigma_{z,pairs}$ by 50\% at $1.5<z<2.5$. We calculate SFRs based on
ultraviolet and ultradeep far-IR $Spitzer$/MIPS and Herschel/PACS data. We
derive rest-frame $U-V$ and $V-J$ colors, and illustrate how these correlate
with specific SFR and dust emission to $z=3.5$. We confirm the existence of
quiescent galaxies at $z\sim3$, demonstrating their SFRs are suppressed by
$>\times15$.
