Abstract
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.
