COSMOS/SMUVS
- The Spitzer Matching survey of the Ultra-VISTA ultra-deep stripes (SMUVS, Ashby et al. 2018) is an Exploration Science Program which collected infrared
imaging with Spitzer's data (Werner et al. 2004) with the Infrared Array Camera (IRAC, Fazio et al. 2004) at 3.6 and 4.5 um over 0.66 deg2 of the COSMOS �field.
- The region covered by SMUVS corresponds to the part of the COSMOS fi�eld with deepest near-IR data from the UltraVISTA program (McCracken et al. 2012) and optical Subaru data (Taniguchi et al. 2007).
- The SMUVS data has an average integration time of 25 h/pointing and reaches 80% completeness at 25.5 mag, both in the 3.6 and 4.5 um �lfilters (Deshmukh et al. 2018).
