9.1. Observation Directions
Output Menu
This option allows the user to set the position of the observation.
-
Spherical observation. If the position of the source has been defined in spherical coordinates, this option will be available. It is possible to define a parametric sweep for one variable (radius, theta or phi) selecting the check box Source Position Sweep. The initial value for R, theta and phi have to be specified.
- Final value: final value for the chosen variable (R, theta or phi).
- Samples: number of samples.

-
Cartesian observation. If the position of the source has been defined in cartesian coordinates, this option will be available. It is possible to define a parametric sweep on t selecting the check box Sweep on 't'. The coordinates x, y and z can be defined with a function which values could depend on the parameter 't'. The initial value for R, theta and phi have to be specified.
- Initial 't': the initial value for t.
- Final 't': the final value for t.
- Samples on 't': number of samples.
