Gaskell model - Produced by Robert Gaskell, Planetary Science Institute
---
The latest version is produced on Jan. 4 2007.
The model is constructed by applying multi-image photoclinometry. The original data has 3,145,728 facets and 1,579,014 vertices, in a text list of plates and vertices.
The original shape model and smaller models reduced in resolution by three grades are stored in the plate-vertex table format (.txt), the STL ASCII format (.stl), and the triangle format (.tri).
Details of the model was described in Gaskell et al. (2006), AIAA paper 2006_6660, AAS/AIAA Astrodynamics Specialists Conf., Keystone, CO, Aug, 2006.
