! PARAMETERS
! ----------
real    :: year_bp_ini   ! Initial year (in Planetary years) of the simulation of the PEM defined in run.def (in Earth years)
real    :: dt            ! Time step used by the PEM in Planetary years
real    :: convert_years ! Conversion ratio from Planetary years to Earth years
real    :: nyears_max    ! Maximal number of iterations when converging to a steady state, read in evol.def
logical :: evol_orbit    ! True if we want to follow the orbital parameters of obl_ecc_lsp.asc, read in evol.def
logical :: var_obl       ! True if we want the PEM to follow obl_ecc_lsp.asc parameters for obliquity
logical :: var_ecc       ! True if we want the PEM to follow obl_ecc_lsp.asc parameters for eccenticity
logical :: var_lsp       ! True if we want the PEM to follow obl_ecc_lsp.asc parameters for ls perihelie
