27 Mar 2003 | | Journal: | Mon.Not.Roy.Astron.Soc. 344 (2003) 527 | | Subject: | astro-ph | | Affiliation: | Univ. of Hertfordshire), R. S. de Jong (STScI), S. Stedman (Hertfordshire), D. M. Bramich (St. Andrews | | Abstract: | We present near-infrared imaging of a sample of 57 relatively large, Northern spiral galaxies with low inclination. After describing the selection criteria and some of the basic properties of the sample, we give a detailed description of the data collection and reduction procedures. The K_s lambda=2.2 micron images cover most of the disk for all galaxies, with a field of view of at least 4.2 arcmin. The spatial resolution is better than an arcsec for most images. We fit bulge and exponential disk components to radial profiles of the light distribution. We then derive the basic parameters of these components, as well as the bulge/disk ratio, and explore correlations of these parameters with several galaxy parameters. | | Source: | arXiv, astro-ph/0303613 | | Services: | Forum | Review | PDF | Favorites | |
