HIS is a sequel to Part IX where the Ephemeris for the physical Observation of Mars from 1 February 2006 to 31 March 2006 was given, and the present one deals with the Ephemeris of one month from 1 April 2006 to 30 April 2006: The data are listed for every day at 00:00 GMT (not TDT). ω and φ denote the longitude and latitude of the sub-Earth point respectively. The symbols λ, δ and ι stand for the areocentric longitude of the Sun, the apparent diameter and the phase angle respectively. In practice, the decimal fractions are not needed except for δ. The phase angle ι is a convenient value to see the noon line or other Martian local times. The apparent declination of the planet is given at the last column, which shows a possible altitude of the planet and as well it may be useful to introduce the planet into the finder. The data are basically based on The Astronomical Almanac for the Year 2006.
