%  Scope:   This MATLAB macro sets the Klobuchar model iono constants.
%  Usage:   ionocon
%  Description of global parameters:
%           alpha  - output, array with 4 components storing the Klobuchar
%                    model alpha constants 
%           beta   - output, array with 4 components storing the Klobuchar
%                    model beta constants
%  Remarks: 1) The constants are taken from satellite 26, subframe 4, page 18,
%              date 5/20/1994.
%           2) The indexes of the arrays alpha and beta are greater than the
%              indexes defined by Klobuchar model by 1 (because Matlab does 
%              not allow a zero index).
