This button allows the user to show or hide the oblique emission settings.

Oblique emission

Note: oblique emission is available only for circular particle sources. For a schematic representation of the oblique emission angles, see the oblique emission section in the Particle Source Emission Model Overview.

Angle theta
The angle theta is formed by the velocity of the emitted particles and the source surface normal.

Angle phi
The angle phi is formed by the component of the particle emission velocity that is perpendicular to the source surface normal and the vector defined by  the center of the circular source O and the emission point.
