How to cull specific vectors with radians

Hallo Dear Rhino Community,

I would need to remove from a list of vectors, which always have the same starting point, and the direction in the same plane, all the vectors included from an angle of 0° (from starting point) to a variable number X[°].
Any advice on how to proceed?

Thanks in advance

A vector has no starting point,
but to know if it is on a plane you’ll have to check if dot product (there is a component) of this vector with plane normal vector equals 0.0 (with a tolerance). Equals 0 means two vectors are perpendicular or null
Then you have a component to measure the angle (0° to 180° or 0° to 360°) of vector relative to another vector.

Have a look at the attachment.
