OortExpansion

class peebee.models.OortExpansion(vert_only=False, **kwargs)

Bases: Model

Oort expansion (alpha) model with flexible vertical and radial components.

Implements a general Taylor series expansion model with vertical acceleration terms and flexible radial rotation curve. The vert_only flag allows using only the vertical potential component.

Methods Summary

accel(x, y, z, **kwargs)	Compute Oort expansion acceleration.
set_vert_only(b)	Toggle vertical-only mode.

Methods Documentation

accel(x, y, z, **kwargs)

Compute Oort expansion acceleration.

Additional keyword arguments

Returns:

acceleration (tuple) - Three-component acceleration (ax, ay, az) in mm/s/yr

set_vert_only(b)

Toggle vertical-only mode.

B (bool):

Enable vertical-only acceleration if True

Returns:

None
