Query: Structure of Bright 2MASS Galaxies: 2D Fits to the Ks-band Surface
  Brightness Profiles   The unprecedented sky coverage and photometric uniformity of the Two Micron
All Sky Survey (2MASS) provides a rich resource for obtaining a detailed
understanding of the galaxies populating our local (z<0.1) Universe. A full
characterization of the physical structure of nearby galaxies is essential for
theoretical and observational studies of galaxy evolution and structure
formation. We have begun a quantified description of the internal structure and
morphology of 10,000 bright (10<Ks<11) 2MASS galaxies through multi-component
model fits to the 2D surface brightness profiles using GIM2D. From our initial
Monte Carlo tests on 77 galaxies drawn at random from the RC3, we find that the
model derived structural parameter errors due to sky uncertainies are typically
less than 10%.
