Combined with the existing panchromatic images for each of these survey fields, available from ground- and space-based facilities, we then generate high quality Spectral Energy Distributions (SEDs) for individual galaxies, spanning the wavelength range from UV to mid-infrared (0.1-8.0 microns). These photometric data will then be used to measure the photometric redshift, stellar mass, rest-frame flux, star formation rates, dust extinction and spectral type for individual galaxies. The result will be self-consistent and uniform catalogues for each survey, containing all these parameters. The target fields include: GOODS-N, GOODS-S, COSMOS, HUDF, AEGIS and the ACS cluster survey. We use the Template FITting technique (TFIT) to perform consistent multi-waveband photometry on images with widely different resolutions (i.e. PSFs). The result is catalogues with the depth and spatial resolution of the ACS images and consistent (PSF-matched) photometry across the wavelength range. The final catalogues for different surveys (field and clusters) can be securely combined or directly compared. Therefore, it will provide a major resource for research. The catalogues will be provided to the community and the STScI archive with the required documentation and the necessary interface to easily access them. These catalogues will provide the community with the required resources to address the most fundamental scientific questions.
