%DSSTARTUP   Double spike startup - defines a number default parameters in global ISODATA
%    DSSTARTUP(...)
% This function creates the global variable ISODATA, which contains
% a number of parameters used in all the double spike calculations.
% ISODATA is a structure, with fields of the form ISODATA.(element).(property)
% e.g. ISODATA.Fe.isonum contains the isotope numbers for Fe: [54 56 57 58]
% Other properties include
%   mass -- the atomic masses
%   standard -- the standard composition (got from 'maininput.csv').
%   rawspike -- the composition of available spikes e.g. from Oak Ridge National
%               Labs (also got from 'maininput.csv').
%   errormodel -- the coefficients used in the error model.
%
% Any arguments that are specified are passed to seterrormodel(), the function
% which specifies the error model. This is useful for setting the beam intensities,
% integration times etc.
%
% Example
%    dsstartup();
%    global ISODATA;
%
% See also errorestimate, optimalspike, seterrormodel
