diff. rotation dΩ 0.2656 0.2974

Notes. Listed are expectation values and 1-σ uncertainties. Latitudes β are derived from the assumed law of differential rotation (Eq. (2)). Periods P are given in days, the spot intensity κ is in units of the intensity of the unspotted surface. The differential rotation dΩ (rad d-1) is the equator-to-pole value of the shear.


The skewed error estimates for the latitude of the second spot are calculated under the assumption that it is located south of the equator.
