Besides the references, adjusted the propellant mass used to calculate the empty mass of stage 1 to 3,400,000 kg, which is what it should be. Adjusted the max payload to 100.000 kg for now in the empty mass calculation as well to adjust for the unrealistic empty weight of stage 1 that would result otherwise.
