EclipticLatitudeConstraint

class m4opt.constraints.EclipticLatitudeConstraint(*args)

Bases: LatitudeConstraint, GeocentricTrueEclipticConstraint

Constrain the ecliptic latitude of the target.

This is the angle \(β\) of Leinert et al. (1998), Fig. 2 [1].

Notes

If the maximum angle is less than the minimum angle, then they are swapped.
