% the number of intersection points on each alpha and gamma curve
Alpha = [8 9 9];
Gamma = [7 7 7];


% input the intersection points of each beta curve with the alpha and
% gamma curves, in order

% the first field says which curve is intersected, in order; gamma curves 
% have a minus sign

Beta(1).curve = [-1 1 -2 2 3 -3 3 2 1 -1 -3 3 -2];

% the second field says which point on each alpha or gamma curve is 
% being hit by the beta, in order

% the sign is +1 for an alpha intersection going up or
% a gamma intersection going outward; -1 otherwise

Beta(1).point = [4 -4 -6 8 -7 5 -5 4 -6 5 2 -2 4];
