[validx,validy,resnormx]=sortvalidpoints(fitxy)

function [validx,validy,resnormx]=sortvalidpoints(fitxy)

% This function will free the good peaks from fitxy, captured by
% peak_labelling, and send them back as validx and validy. The loops you
% will find are not absolutely necessary and reduce the speed of this
% function tremendously and will be changed probably in a future version if
% there is need.
