Looks good but we should double-check the formula, if we could get a confirmation from Finn it would be nice but that may not be possible

This docstring should match the param name

Finn might've made a mistake with his formula, this simplifies to frequency_hz * (relative_velocity_m_s / speed of light), but I'm pretty sure it's frequency_hz * (speed of light / (speed of light + relative_velocity_m_s))

We're trying to get the observed frequency itself but this seems closer to an approximation of the shift
