Abstract:
We investigate the scaling relations of bulge and disk structural
parameters for a sample of 108 disk galaxies. Structural parameters
of individual galaxies are obtained from two-dimensional bulge/disk
decomposition of their H-band surface brightness distributions. Bulges
are modelled with a generalized exponential (Sersic) with variable
integer shape index n.
Description:
We present the results of the photometric deconvolution of the sample
galaxies. The given surface brightnesses are corrected to face-on
assuming full transparency. No correction is applied for internal
extinction. Magnitudes and surface brightnesses are corrected for
extinction within our Galaxy and for redshift dimming.
