ACS GTO Science Data Archive Visualization Tools

Terence Allen, Kenneth Anderson, W. Jon McCann .

The ACS GTO Science Data Archive (SDA) offers access to all products generated by the ACS GTO data processing pipeline (APSIS) through a database-driven web interface. It enables science team members to construct ad hoc and deeply structured queries through visually intuitive navigation and search tools. The current capabilities include: color and magnitude constrained object searches, cross-correlated searches with other online catalogs, direct download access to all FITS images, download of complete object catalogs and search results in a variety of formats (including VOT, HTML, XML, CSV). The web interface comprises a suite of tools that have been developed for the SDA to supplement the core functionality of the archive. We will demonstrate tools that provide such functionality as on-the-fly color image generation, clickable object maps, image cutouts of cataloged objects, object aperture and wcs data overplotting, arbitrary image zooming, scaling and color bias, user-selectable image intensity scaling/stretching, data product pedigree charting and dynamically generated data product inventories. The recently added functionality of allowing a user to fine tune the full color maps which are generated on the fly has proven its scientific worth: a selection of scales and scale stretches has aided in the visual identification of AGNs and other. \
