    ... Interesting article - thanks! SkyMap uses the standard IAU magnitude formulae for Mercury and Venus. These are known to be rather inaccurate at low

      Interesting article - thanks!

      SkyMap uses the "standard" IAU magnitude formulae for Mercury and
      Venus. These are known to be rather inaccurate at low phase, but they
      are the "standard" ones which everybody uses, hence they will be the
      same values given by publications such as the "Astronomical Almanac".
