Abstract We seek imaging of the William Herschel Deep Field (WHDF) with the ACS to primarily determine morphological and structural parameters of a sample of 94 late-type galaxies brighter than R=23 with redshifts up to z=1. We already obtained spectra of the galaxies at ESO's VLT from which spatially resolved rotation curves are derived. Only the combined VLT and ACS data allows us the construction of the Tully-Fisher Relation (TFR) at intermediate redshift. Together with 77 galaxies from the FORS Deep Field (FDF), for which we already have ACS determined structural parameters, we will have the hitherto largest kinematic sample to investigate significantly the evolution of the TFR and the Fundamental Plane of spiral galaxies. The additional WHDF galaxies populate mainly both ends of the TFR (i.e. are slow rotators or bright early-type giants) being indispensible for the verification of an evolving slope as suggested by the FDF sample. Such a difference in the luminosity and mass evolution between dwarf and giant galaxies is a strong constraint to current theories of galaxy formation and evolution. The ACS imaging of the WHDF will boost its scientific impact also with other investigations like the study of the Fundamental Plane of intermediate redshift field elliptical galaxies, the study of the size and type evolution of an even larger sample of galaxies and the study of galaxy-galaxy lensing. ------------------------------------------------------------------------------------ 9908( 3) - 05/08/03 09:13 - [ 2] Observations Description ------------------------ Basic aim is ACS/WFC imaging of 100 target galaxies in the William Herschel Deep Field in the redshift range 0.1 Visit Requirements: PCS MODE FINE SCHED 30% ORIENT 87.0D TO 89.0 D ORIENT 177.0D TO 179.0 D ORIENT 267.0D TO 269.0 D ORIENT 357.0D TO 359.0 D On Hold Comments: Additional Comments: The ORIENTation of the field should be PA=0D +/- 1D modulo 90D. Each target is assigned 1 visit which should fill 1 orbit. Besides guide star acquisition and ACS overhead time, 1 orbit should be split into 2 exposures with equal amounts of time. Telescope position should be shifted by 5 pixel in x and 60 pixel in y between the 2 exposures to fill the intra-chip gap. No further CR-SPLIT is necessary.
