Abstract:
Based on drizzled F606W and F814W images, we present quantitative
structural parameters in the V-band rest-frame for all galaxies with
z<1 and I814(AB)<24.5mag in the Hubble Deep Fields North and
South. Our structural parameters are based on a two-component surface
brightness distribution using a Sersic bulge and an exponential disc.
Detailed simulations and comparisons with previous work are presented.
Description:
Each HDF image consists of a 2.5x2.5arcmin2 Wide Field Planetary
Camera 2 (WFPC2) pointing. The images were acquired through the
broad-band F300W, F450W, F606W and F814W filters. For the present work
we have used the publicly available reduced F606W and F814W Version 2
drizzled images with a sampling of 0.04arcsec/pix and a total exposure
time of 109050s (F606W; HDF-N), 123600s (F814W; HDF-N), 97200s (F606W;
HDF-S) and 112200s (F814W; HDF-S). The high sampling of these images
avoids the undersampling problems affecting other Hubble Space
Telescope (HST) images.
