Euler includes all 12 sequences where within each there are three angles: A, B, C. DCM includes all nine elements of the direction cosine matrix; e.g., XX, XY, etc. AngleAxis includes X, Y, Z components of the unit axis of rotation and RotationAngle. |
| Parameter Set Cartographic Trajectory | Cartographic Trajectory Parameter Set contains calculations that relate a specified point to the selected central body shape.

| Pattern Angle Extremals Intersection | Provides information about the points on the sensor pattern where the dihedral angle reaches its extremal values. This angle called the extremal angle is measured between two planes passing through the origin of the sensor. One of the planes - the reference for this angle - is perpendicular to the ground velocity vector and to the surface normal. The other plane is rotated away from the reference plane through the extremal angle about the direction of the ground velocity vector. |
| Pattern Intersection | Points of the pattern that represent intersection of boundary of the sensor field-of-view with the ground surface. Points are computed in the sensor's central body fixed coordinate system. Additionally, on a Sensor's 2D Graphics Projection properties page, if "Use" is enabled under Extension Distances, points on set altitude projection levels are reported; if Show Intersections is set to Terrain, non-zero altitude values are reported for the pattern intersection and if set to Central Body, the altitude is always 0. |
| Pattern Intersection At Distance | Allows user to select either range or altitude as additional limits for sensor projection. This means that sensor intersection points are computed where the sensor field of view intersects the limiting surface - either range or altitude. |
| Pattern Intersection Extremals | The extremal points of the sensor pattern intersection report, based upon distance. Four extremals are reported at each time step: the first is the most forward point, the second most rightward point, the third the most behind point, and the fourth the most leftward point. The forward extremal is the largest positive value of the alongtrack distance; the leftward extremal is the largest positive value of the perpendicular-to-groundtrack distance; the behind and leftward extremals are defined analogously, using the largest negative values. Note that it is possible to have multiple points on the pattern located at the same extremal angle; however, the data provider will still return only a single point for each extremal direction. |
