The error of the efficiencies is mainly due to an uncertainty of the brightness temperature of the planet.

  1. Brightness Temperatures (Tb) of the Source (We used temperatures compiled by Shibata 1990)
    Mars
  2. The Diameter of the Planet
    The value is taken from the "Calender and Ephemeris" provided by ECO, NAOJ.
