    Andrés,

    It is possible to discover systematic error on a two body fix. This is done by taking a back sight on one of the bodies observed (needs an Hs above 60°). The difference in moa between the plotted parallel LOP divided by 2 will be the systematic error which can then be applied to the second observed body (of any Hs) to get an improved two body fix.
