Function source_dop 

pub fn source_dop(
    sensors: &[Sensor],
    source_position_m: &[f64],
    propagation_speed_m_s: f64,
) -> Result<Dop, SourceLocalizationError>

Compute timing DOP for a proposed source location.

The returned position DOP values multiply timing sigma in seconds to produce metres. The local Cartesian axes are used for the horizontal and vertical split.

Errors

Returns SourceLocalizationError::InvalidInput for malformed, non-finite, inconsistent inputs, including a source coincident with a sensor. Returns SourceLocalizationError::Geometry when the shared DOP machinery finds too few sensors or a singular timing design.
