Here is a macro that does this:

    setRGBWeights(1, 0, 0);
    red = getProfile;
    setRGBWeights(0, 1, 0);
    green = getProfile;
    setRGBWeights(0, 0, 1);
    blue = getProfile;
    f = File.open(getDirectory("home")+"profile.xls");
    for (i=0; i<red.length; i++)
        print(f, red[i]+"\t"+green[i]+"\t"+blue[i]);
