!+ ! ! bin_solve.sfit ! An example SFIT input file for fitting composite spectra ! ! Purpose: != compute Teff, log g, etc, for both componets in a compositte spectrum ! using lines in the wavalength range: 3800 5200 ! a high resolution echelle spectrum ! and assuming the new (STERNE2 + LESTER) LTE model grids ! ! :: NB the Opacity Sampling Grid will come soon. ! ! Mode: ! SLV / AMOEBA ?? / HIRES ! ! Method: ! Read in a model atmosphere grid for the hot star ! Read in a model atmosphere grid for the cool star ! Read in a hires optical spectrum ! Uses amoeba to find optimum model ! ! ** WARNING ** ! This example is not yet suppplied with test data and has not ! been proven in action. The methods were used successfully in ! real applications (BI Lyncis and other sdBs) and published. ! ! Jeffery & Aznar Cuadrado 2001, A&A 378, 936. ! Aznar Cuadrado & Jeffery 2002. A&A 385, 131. ! !
