Help: ALTWG Tools version 76219 (built on 2020-Aug-13) usage: ViewingGeometryPerFacet [options] -date <arg> Required. Observation date. Format can be anything readable by the SPICE str2et method. -frame <arg> Shape model reference frame. Default is IAU_{target}. -logFile <arg> If present, save screen output to log file. -logLevel <arg> If present, print messages above selected priority. Valid values are ALL, OFF, SEVERE, WARNING, INFO, CONFIG, FINE, FINER, or FINEST. Default is INFO. -obj <arg> Required. Shape model for target body. -observer <arg> Required. SPICE name of observer. -output <arg> Output filename. Default is to print to console. -spice <arg> SPICE kernel(s) to load. Multiple kernels may be specified separated by whitespace. -target <arg> Required. SPICE name of target. This program calculates the viewing geometry for a shape model at each facet visible from the observer. |
ViewingGeometryPerFacet outputs similar data to GetSpots, but also includes lat/lon of each facet center. The inputs and outputs are formatted different.
