Abstract
We present deep |$J$|-, |$H$|-, and |$K_{\rm s}$|-band imaging data of the MOIRCS Deep Survey (MODS), which was carried out with the Multi-Object Infrared Camera and Spectrograph (MOIRCS) mounted on the Subaru Telescope in the GOODS-North region. The data reach 5|$\ \sigma$| total limiting magnitudes for point sources of |$J$||$=$| 23.9, |$H$||$=$| 22.8, and |$K_{\rm s}$||$=$| 22.8 (Vega magnitude) over 103 arcmin|$^{2}$| (wide field). In 28 arcmin|$^{2}$| of the survey area, which is an ultra-deep field of the MODS (deep field), the data reach 5|$\ \sigma$| depths of |$J$||$=$| 24.8, |$H$||$=$| 23.4, and |$K_{\rm s}$||$=$| 23.8. The spatial resolutions of the combined images are FWHM |$\sim\ $|0|$''\!\!\!.$|6 and |$\sim\ $|0|$''\!\!\!.$|5 for the wide and deep fields in all bands, respectively. Combining the MODS data with the multi-wavelength public data taken with the HST, Spitzer, and other ground-based telescopes in the GOODS field, we constructed a multi-wavelength photometric catalog of |$K_{\rm s}$|-selected sources. Using the catalog, we present |$K_{\rm s}$|-band number counts and near-infrared color distribution of the detected objects; we also demonstrate some selection techniques with the NIR colors for high redshift galaxies. These data and catalog are publicly available via Internet.
