NIR surface photometry of a sample of nearby spiral galaxies

摘要: The first results of an observational programme aimed at mapping a sample face-on spiral galaxies in the NIR are presented. This paper shows surface photometry ten sample. data were taken broad band J (1.2 µm) and Ks (2.2 filters. sources selected mainly according to their size brightness order suit characteristics CAIN 2D camera on 1.5-m Carlos Sanchez Telescope (Tenerife, Spain). primary scientific goal is provide comprehensive uniform database main structural photometric parameters members from photometry. To this end, elliptical isophotal fitting was performed each galaxy image extract information about location its morphological components azimuthally averaged radial profile. Analytical functions for component's distribution then used match that profile, functional obtained global fitting. report includes NGC 3344, 3686, 3938, 3953, 4254, 4303, 4314, 5248, 6384 7479.
