We can derive the equation from that for the precisional rate each year. In my research I have found that its a Sine curve and is even modulated by another curve of very long wave length. Thus the crest and trough of the sine curve goes up and down with time. Possibly I can share my finding on the nature of precision with you later. Even though we can arrive at the rate of precision, but the actual ayanamsa would depend on our identification of the first point of Aries, whether it is shown by a star in Revati or oppositite of Chitra or a star in Aswini. Different authors have different viewpoints. For the time being I take opposite of Chitra. I would say the star showing that should be closer to the ecliptic plane in terms of declination.

Dear Visti, Namaskar,

If the theory of Binary star is correct, we can apply kepler’s law of areas to find out the speed of Sun at various times revolving around another star. We can derive the equation from that for the precisional rate each year. In my research I have found that its a Sine curve and is even modulated by another curve of very long wave length. Thus the crest and trough of the sine curve goes up and down with time. Possibly I can share my finding on the nature of precision with you later.

Even though we can arrive at the rate of precision, but the actual ayanamsa would depend on our identification of the first point of Aries, whether it is shown by a star in Revati or oppositite of Chitra or a star in Aswini. Different authors have different viewpoints. For the time being I take opposite of Chitra. I would say the star showing that should be closer to the ecliptic plane in terms of declination.

Best regards

Thereafter, we need to compare the current precession rate with those values from these orbital values, and finally we will be able to ascertain the correct ayanamsa. With Keplers law of areas we can get very close to these with the current values that we have. Yours sincerely, Visti Larsen. हरे राम कृष्ण

If we can even decide on the right starting point of Aries, other computation can be taken care of by the actual astromical position of the stars. Well narrated.

The Binary Research Institute, which i mentioned in my writeup is working with this, and have made some nice publications regarding the same. All other softwares can use ephemeris without any problems, but its up to the programmers to implement this. The most popular ephemeris is the Swiss Ephemeris: http://www.astro.com/swisseph/?lang=e They have based their data on Nasa's Jet Propulsion Laboratory. Yours sincerely, Visti Larsen हरे राम कृष्ण॥

What prevents the other Jyotish softwares apart from JHora to follow the ephemeris with actual star positions? Is the actual ephemeris created using satellite images with fine tuned granularity? Aum Ganeshaya namah, Rajagopal Pranams Vistiji,

Good to hear from you. I had made a typo in the above writeup and said that the mean-motion of planets was in vogue. This offcourse should read: mean motion of ayanamsa. As for Ramans Ayanamsa. My main point reg. it is that Raman never openly said that this was a new ayanamsa. His students did. Also earlier he had used calculations based on Lahiri. Therefore, how can we know whether he actually meant to introduce a new ayanamsa? We don't need computers to calculate an accurate ayanamsa for a given year. For thousands of years the practice in vogue (and given in the Surya Siddhanta) was to depict the night-star positions on stone tablets, and wait until the equinox point which occurs every six months. Since that day had a day and night of equal length it was different from other days and could be used for reference. Some other days like the 25th of December also has a distinct peculiarity and can be used as reference for the tropical entry into Capricorn. Thereby, by having a day of reference and a star position as reference one can depict the ayanamsa for the given time. This was then used until the next equinox. Thank you for the precession rates given by Krishnamurti. But where did he get them from? Yours sincerely, Visti Larsen. हरे राम कृष्ण॥
