Guest guest Posted March 7, 2009 Report Share Posted March 7, 2009 Dear Friends, I have noted that most of the programs are using the precession rate given by Newcomb i.e 50.2388475 sec per year. Since the definition of Simon Newcomb, in regard to the precise expression of the speed of general precession in longitude, remarkable progress has been achieved in one century. The curerent value of precession as per IAU for 2009 as well as that published by US Naval Observatory is 50.28796195 per Julian year.(refer http://asa.usno.navy.mil/SecK/2009/Astronomical_Constants_2009.txt as well as IAU XXIV General Assembly (2000) resolutions B1.5, B1.6, B1.9, & IAU2000A precession-nutation) which is quite different, even after considering annual correction of .000111 sec per year. As such the ayanamsa figures will have a differance of about 4 seconds from epoch 1900 to that of now. Which may affect sub-sub lord in many cases. I would also like to draw attention of learned members that the Swiss ephmeris in regard to Krishnamurthy Ayanamsa has stated as follows in its documentation/mauals (refer ftp://ftp.astro.ch/pub/swisseph/swisseph.doc): QUOTE There are a few more ayanamshas, whose provenance is not known to us. They were given to us by Graham Dawson ( " Solar Fire " ), who took them over from Robert Hand's Program " Nova " : 2) De Luce 3) Raman 5) Krishnamurti UNQUOTE I could not find out the exact/source of algorithm used by Robert Hand's program. But this is to highlight that in my experience the results of Swiss Eph. for KP do not match to those given in " Astrological Tables for All by Shri Eshwara Manu " published with the blessing of Guruji KSK ( supposed to support a maual calculation of the Old KPA value correct to seconds) Views of learned members are solocited in this respect to make programs more accurate by adopting current values which have been given by Lieske and adopted by IAU as far as KP ayanamsa is concerned. regards Amitabh 09906908910 , " tw853 " <tw853 wrote: > > Dear Swami ji, > > 1.
