Optimization Run Input File Format

To submit an optimization run to AMP, the observational constraints must be uploaded in an ASCII text file using the following format:

  • The first line must be an integer that describes number of seismic observables in the file.
  • The subsequent lines describe the mode of degree, frequency, and error for each observable. The degree is an integer 0, 1, 2, or 3; the frequency and error are Fortran-style double-precision numbers ending with "d0".
  • Optionally, the non-seismic constraints may follow the seismic observables. The first column must consist of a character: "T" (Teff), "L" (L/Lsun), "R" (R/Rsun), "M" ([M/H]), or "G" (log g). This is followed by the value and the error as Fortran-style double-precision numbers ending with "d0".
  • Lines starting with the # character are ignored.

For example:

          0 2093.50d0 0.16d0
          0 2228.77d0 0.18d0
          0 3574.90d0 0.55d0
          1 2156.78d0 0.17d0
          2 3567.01d0 0.57d0
          2 3703.30d0 0.89d0
          T 5777.00d0 100.d0
          L 1.00000d0 0.01d0

Note that the first line may also contain up to an additional six parameters that control the simulation. These are:

  • flag_weights
  • flag_surface
  • flag_diffusion
  • delta_nu_in
  • flag_overshoot
  • alpha_ov
