The Galaxy Halos, Outer disks, Substructure, Thick disks and Star clusters (GHOSTS) survey (P.I. Roelof de Jong, Space Telescope Science Institute) is providing definitive HST analysis of extra-planar stellar populations of nearby disk galaxies. HST programs 9765, 10523, and 10889 are associated with the survey.

The GHOSTS team has provided a website with a variety of images, diagnostics, catalog information and access to the data. The GHOSTS data products are described in this web page. The data are directly available at

MAST has supplemented this webpage with links to an HLA-like interactive display of the various fields. This page also includes links to the related GHOSTS web pages.
