The volume of thermal contraction calculated from the maximum value of Λ is shown in blue, and the volume of contraction assuming a minimum is shown in green. Using Λmin requires an initial starting radius of 0.944 km, and Λmax results in an initial radius of 2.386 km. a Thermal model over a period of 20 years. b Model fit over the observation period
