Emission heights (radial distance from the centre of the star) for a cone originating at the last open field line (magnetic latitude θp). For any other starting magnetic latitude θ0, r(θ0) ≈ r(θp) × (θp/θ0)2. The emission heights at frequencies above the LBA band were extrapolated from the parameters derived from the LBA data.
