Overview

ab_finder runs moog with the abfind driver in an iterative fashion to
determine the optimum model atmosphere parameters for a given set of
lines.

The sample_input directory contains sample input files for use with
ab_finder.  The 

Options:
  -h, --help            show this help message and exit
  -m MOOG_EXE, --moog=MOOG_EXE
                        The path to the moog executable.  Default:
                        moog/MOOGSILENT
  -a ATMOSPHERE_EXE, --atmosphere=ATMOSPHERE_EXE
                        The path to the model atmosphere generator.  Default:
                        castelli_mod/castelli
  -p PARAMETER_FILE, --parameter-file=PARAMETER_FILE
                        The path to the moog parameter file.  Default: sun.par
  -o OUTPUT_FILE, --output-file=OUTPUT_FILE
                        The path to the log file.  Default: results.dat
  --line-sigma=LINE_SIGMA
                        Maximum deviation for line clipping.  Default: 2.0
  --no-clip             If given, do not perform line clipping.
  --ion-ratio=ION_RATIO
                        The abundance ratio to be minimized by varying the
                        surface gravity.  This must be given with quotes.
                        Default: "Fe I/Fe II"

  Initial atmospheric parameter guesses:
    --initial-temp=ATMO_INIT_TEMP
                        Initial temperature guess.  Default: 6000.0
    --initial-Z=ATMO_INIT_MET
                        Initial metallicity guess.  Default: -0.001
    --initial-logg=ATMO_INIT_LOGG
                        Initial surface gravity guess.  Default: 4.0
    --initial-vturb=ATMO_INIT_VTURB
                        Initial microturbulent velocity guess.  Default: 1.0
