Query: Early type galaxies and structural parameters from ESO public survey
  KiDS   The Kilo Degree survey (KiDS) is a large-scale optical imaging survey carried
out with the VLT Survey Telescope (VST), which is the ideal tool for galaxy
evolution studies. We expect to observe millions of galaxies for which we
extract the structural parameters in four wavebands (u, g, r and i). This
sample will represent the largest dataset with measured structural parameters
up to a redshift $z=0.5$. In this paper we will introduce the sample, and
describe the 2D fitting procedure using the 2DPHOT environment and the
validation of the parameters with an external catalog.
