Abstract:
This paper describes new deep 3.6 and 4.5µm imaging of three
UltraVISTA near-infrared survey stripes within the COSMOS field. The
observations were carried out with Spitzer's Infrared Array Camera
(IRAC) for the Spitzer Matching Survey of the UltraVISTA Deep Stripes
(SMUVS). In this work we present our data reduction techniques, and
document the resulting mosaics, coverage maps, and catalogs in both
IRAC passbands for the three easternmost UltraVISTA survey stripes,
covering a combined area of about 0.66deg2, of which 0.45deg2 have
at least 20hr of integration time. SMUVS reaches point-source
sensitivities of about 25.0 AB mag (0.13µJy) at both 3.6 and
4.5µm, with a significance of 4σ, accounting for both survey
sensitivity and source confusion. To this limit the SMUVS catalogs
contain a total of ∼350,000 sources, each of which is detected
significantly in at least one IRAC band. Because of its uniform and
high sensitivity, relatively large area coverage, and the wide array
of ancillary data available in COSMOS, the SMUVS survey will be useful
for a large number of cosmological investigations.
Description:
Since the first visit with IRAC in Cycle 2, the Spitzer mission has
spent nearly 4000hr surveying COSMOS. Roughly 1770hr of Spitzer time
(spanning 2005 Dec to 2017 Mar) were devoted to the new Spitzer
Matching Survey of the UltraVISTA Deep Stripes (SMUVS) observations
described here.

Note (3): Code as follows:
0 = no known issues with the photometry.
1 = possible corrupted photometry due to proximity to a bright star.
2 = a bright (>23 AB mag) single-band detection.
3 = a different single-band detection, i.e., a faint (<23mag) one.
See section 7 for further explanations.
