Spitzer Matching survey of the UltraVISTA ultra-deep Stripes (SMUVS):
  Full-mission IRAC Mosaics and Catalogs
  This paper describes new deep 3.6 and 4.5 micron 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 Ultra-VISTA 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 0.66 square
degrees, of which 0.45 square degrees have at least 20 hr integration time.
SMUVS reaches point-source sensitivities of about 25.0 AB mag at both 3.6 and
4.5 microns with a significance of 4-sigma accounting for both survey
sensitivity and source confusion. To this limit the SMUVS catalogs contain a
total of about 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. We will make all images and catalogues described herein
publicly available via the Spitzer Science Center.
