- chip_from_q_component_spins(q, a1, a2, ct1, ct2, math=<module 'numpy' from '/usr/share/miniconda/envs/__setup_conda/lib/python3.9/site-packages/numpy/__init__.py'>)[source]#
Calculate the effective precessing spin, \(\chi_\mathrm{p}\), from the mass ratio, component spin magnitudes and tilts.
- Parameters:
- qarray_like
Mass ratio (defined from 0 to 1).
- a1array_like
Spin magnitude of the primary component.
- a2array_like
Spin magnitude of the secondary component.
- ct1array_like
Cosine of the spin tilt of the primary component.
- ct2array_like
Cosine of the spin tilt of the secondary component.
- mathmodule, default=`numpy`
Math module to use.
- Returns:
- array_like
Effective precessing spin.
