J/MNRAS/355/82      Morphological analysis of HDF-N and HDF-S  (Trujillo+, 2004)

Quantitative morphological analysis of the Hubble Deep Field North and Hubble Deep Field South - I. Early- and late-type luminosity-size relations of galaxies out to z∼1. Trujillo I., Aguerri J.A.L. <Mon. Not. R. Astron. Soc., 355, 82-96 (2004)> =2004MNRAS.355...82T

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. File Summary:
