ADC_Keywords: Galaxies, IR ; Photometry, infrared Keywords: galaxies: photometry - galaxies: structure - infrared: galaxies - surveys Abstract: This paper presents empirical results from a deep imaging survey of galaxies in the local universe at the J and Ks wavelengths. Three hundred ninety-one images have been obtained and calibrated using the same camera and filter set with the Steward Observatory 1.6m Kuiper Telescope on Mount Bigelow and the 2.3m Bok Telescope on Kitt Peak. The limiting magnitude is typically 22mag/arcsec at J and 21mag/arcsec at Ks. The central surface brightness, apparent magnitudes, sizes, scale lengths, and inclinations are tabulated from measurements made using these data. The purpose of this paper is to provide basic near-infrared data on a variety of galaxy types. File Summary:

Note (1): Gives the UGC number along with the date on which the data were taken. For example, u10j.10.1819.99.fits is an image of UGC 10 taken with a J filter on October 18-19, 1999. Note (2): From the IRAF STSDAS ellipse fit at the level of 2σ above the pixel to pixel noise. Note (3): The dimensions of the elliptical aperture and sky annulus were selected interactively, while viewing the image, so that the galaxy was included within it and that no stars were included in the sky annulus. Note (4): It is the total brightness per square arcsecond in the center of the galaxy. For those galaxies which have bulge and disk components it includes contributions from both of them. Note (5): Obtained by running the STSDAS task ellipse on the image to obtain a radial profile of brightness versus distance from the galaxy center. The quantity Rad was then calculated to be the integral of the distance from the center times the flux at that distance divided by the integral of the flux. The integral was carried out to the isophotal limit.
