Parameter spaces and analysis for eta_0 values

<b>Instructions to data:</b> All data are saved in the folder "./datainfo". The data files with a prefix "All_Finalised_Cases" contain the information of thermal evolution read from the modeling cases that can maintain the Martian mantle convection to be active until now.<b>Instructions to Python scripts:</b> The Python scripts with a prefix "ParameterSpaces" are used to generate the parameter spaces of initial mantle temperature, reference viscosity, super-heating magnitude at the core-mantle boundary (CMB), present-day mantle potential temperature, initial mantle water content and present-day mantle water content for different primitive crust thickness. The postfix notes the states of the primitive crust. For example, "DensePrimitiveCrustZeta1" represent the dense primitive crust with an enrichment factor of 1.0. These scripts will also save the successful cases as the data files in "./datainfo", with the prefix "Successful_Cases".All Python scripts must be run by Python 3 with Numpy, Matplotlib and Pandas.
