(HP-67/97) Planetary Ephemeris

[Josef]

Yes, you have a right. I am now preparing a much better version of the calculation of the Sun's position that is significantly more accurate. Unfortunately, fitting the positions of the planets and Sun into one program in 224 steps with reasonable accuracy is impossible. The author did not give the exact algorithm for calculating the positions, it could be reverse decoded, but it is better to write the program again and better.
