Using GIM2D, the images are fitted with two-dimensional surface-brightness models consisting of a simple disc and bulge component to derive the fraction of luminosity in the bulge B/T. Description: We selected our sample from the catalogue of Goto et al. (2003PASJ...55..771G), based on the first data release of the Sloan Digital Sky Survey (Abazajian et al., 2003AJ....126.2081A, see http://www.sdss.org). Observations were made with the UFTI near-infrared imaging spectrograph on the United Kingdom Infrared Telescope (UKIRT) over two semesters. File Summary:

Note (1): Uncertainties on Ksmag are limited by the zero-point and are ∼0.08mag Note (2): Note that these are meaningless in irregular systems (such as close pairs or mergers) Note (3): Where positive numbers represent absorption. Note (4): From the SDSS pipeline, with positive numbers indicating emission Blank entries ('-') correspond to undetected emission lines.
