nuance.Star.min_radius

Star.min_radius(period: float, SNR: float, N: int, sigma: float) → float

Given a target SNR and periods, returns the minimum planetary radius detectable (in \(R_\oplus\)).

Parameters:

• period (float) – planet orbital period in days

• SNR (float) – signal-to-noise-ratio

• N (int) – number of points observed

• sigma (float) – observation error

Returns:

radius is earth radius

Return type:

float
