Function chan_ho_initial_guess 

pub fn chan_ho_initial_guess(
    sensors: &[Sensor],
    arrival_times_s: &[f64],
    propagation_speed_m_s: f64,
    mode: SourceSolveMode,
) -> Result<SourceInitialGuess, SourceLocalizationError>

👎Deprecated since 1.1.0:

use closed_form_initial_guess; this is Schau-Robinson spherical intersection, not Chan-Ho

Deprecated name for closed_form_initial_guess.

The implemented initializer is the Schau-Robinson spherical-intersection linearization, not the two-stage Chan-Ho weighted least-squares method.

Errors

Returns the same SourceLocalizationError variants as closed_form_initial_guess.
