| Abstract: |
Montage will deliver a generalized toolkit for generating on-demand, science-grade custom astronomical image mosaics. ``Science-grade'' in this context requires that terrestrial and instrumental features are removed from images in a way that can be described quantitatively. ``Custom'' refers to user-specified parameters of projection, coordinates, size, rotation and spatial sampling, and whether the drizzle algorithm should be invoked. The greatest value of Montage will be its ability to analyze images at multiple wavelengths, by delivering them on a common projection, coordinate system and spatial sampling and thereby allowing analysis as if they were part of the same multi-wavelength image. Montage will be deployed as a compute-intensive service through existing portals. It will be integrated into the emerging NVO architecture, and run operationally on the Teragrid, where it will process the 2MASS, DPOSS and SDSS image collections. The software will also be portable and publicly available. |
