  1. For each evaporation of Pb, we give the mass, the heat capacity Cp at 7.5 K, the βi used in the equation Ci(T)=βiT3 for the fit, the thickness t, the heat capacity jump ΔCp at Tc, the specific heat jump Δcp at Tc, the resistance per square Rsq and the Tc extracted from the heat capacity measurements.
