    To which he has replied:

    Sure, but this discussion was based on the next step, after those
    errors were already eliminated leaving only random error to be

    Gary, I think you are confused here. Error can be split up into systematic (constant) and random. Either can be significant.

    The distinction is important as the method of resolving them is different. Both should be resolved as much as possible since this will lead to position lines in which one can have more confidence, that are closer approximations to the position.
