Relative to the center of the Earth, then it geocentric. A topocentric position is relative to an observer on the surface of the Earth. Within the aim of our accuracy of 1-2 arc minutes, the difference between geocentric and topocentric position is negligible for all celestial bodies except the Moon (and some occasional asteroid which happens to pass very close to the Earth). The orbital elements consist of 6 quantities which completely define a circular, elliptic, parabolic or hyperbolic orbit.

For eclipses occultations, there are likely to be significant differences depending where on the Earth (or wherever) you are standing.

Also, light time is not included yet in the body positions, and this can have potentially noticeable effects for multibody or distant occultations. The image looks too

Very small indeed, if the limit is raised. Or in other words Despite the too low Chi-square, the prime numbers still can be regarded, according to this test, as randomly distributed. A consequence of this research is that it should be possible to base a new kind of randomness test by picking 167 prime numbers at random from stored in a file by a (P)RNG and do the Chi-square with three degrees of freedom on the obtained last digit distribution. Do this test a 1000 times and calculate the

Actually the correct list for n? is n=2, 3, 5, 7, 13, 17, 19, 31, 61, 89, 107, 127. Now we move to perfect numbers for a second. Ancient mathematicians found that some numbers equalled the sum of their divisors. These numbers are called perfect numbers. Six is the first perfect number, 6=1+2+3 and the next is 28=1+2+4+7+14.
