This directory contains grand solution software, which deduces stellar parameters by fitting stellar spectra obtained with an iodine cell.

Documentation (in progress) is available at http://cadence.caltech.edu/~bfulton/pydocs/grandsol/

The fitting code 'grandsol/fort/grand' determines: intrinsic stellar spectrum (a.k.a. deconvolved template) stellar radial velocity for each epoch wavelength solutions for each epoch crude continuum normalization for each epoch line spread functions across the echelle format for each epoch

Brief descriptions of 'grandsol' subdirectories: 'fort' - fortran source code for the fitting code 'grand.F' 'fref' - reference files used by the fortran code 'grand'

See README files in each subdirectory for more information.
