EROS MSI IMAGES WITH GEOMETRY BACKPLANES

This data set contains data products for 93,397 images obtained by the Multi-Spectral Imager (MSI) of the Near Earth Asteroid Rendezvous (NEAR) mission during the orbital phase at asteroid 433 Eros. The data products include geometric and geophysical information for each pixel. The data products are in the form of backplanes, stored in the FITS image format. There is one backplane file for each MSI image. Each of the MSI backplane files is a 16-band image cube. The bands of the cube contain the information detailed below calculated for the center of each pixel: 1: Pixel values (I/F) of the original FITS images delivered to the PDS by the NEAR team [Murchie et al., 2001], linearly resampled to rectify the image by squaring the pixels. The original image size is 537 x 244 pixels and the rectified size is 537 x 412 pixels. 2: x coordinate (kilometers) of the intercept with the surface of the asteroid in body-fixed reference frame 3: y coordinate (kilometers) of the intercept with the surface of the asteroid in body-fixed reference frame 4: z coordinate (kilometers) of the intercept with the surface of the asteroid in body-fixed reference frame 5: latitude (planetocentric, degrees) 6: longitude (degrees east) 7: radial distance (kilometers) from the asteroid center of figure 8: solar incidence angle (degrees) 9: emission angle (degrees) 10: solar phase angle (degrees) 11: horizontal pixel scale (kilometers) 12: vertical pixel scale (kilometers) 13: average surface slope relative to gravity (degrees) 14: average elevation relative to gravity (meters) 15: average gravitational acceleration (meters/[s^2]) 16: average gravitational potential (J/kg)
