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.

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.
