Guest guest Posted April 14, 2005 Report Share Posted April 14, 2005 Dear Wendy and All, For all the esteemed astrologers here, I would like to put forth a dilemma that I am having with calculating a Lahiri Ayanamsa. It is quite detailed to the best of my acknowledge. Sorry for being so dry – but it is really important to me – to get it all sorted out. First let me say - I have my computer programs set at True Node; Lahiri ayanamsha. 365 days. I have three Vedic computer programs and both an American sidereal Ephemeris and a Lahiri Sidereal Ephemeris book that conflict each other in Dasha timing because of Ayanmasha calculation. The lahiri Sidereal Ephemeris book uses planetary calculations from Jean Meeus Astronomical Algorithms. It uses Julian Day and Universal Time vs. Ephemeris Time. So timing varies with earth rotation etc vs. constant rate. It uses apparent Longitude and Latitude as seen from the earth and not its actual position of movement. It also uses the yr 200AD to calculate when the Spring equinox was Pisces. Current: 4/01/2005 Lahiri ayanamsha: 23* 55.5' - Delta T 71 seconds, Julian date: 1885.5 - Sidereal Tiime: 12 37 48' I would say that this lines up more with American sidereal Calculations but no that ephemeris book I have is different too. All of their computations are taken from the ACS atlas. It uses Julian Day and Universal Time for the Sidereal Time. However, all its planetary positions and aspects along with moon phenomena are given for Midnight Ephemeris Time. Moon on the other hand is given Ephemeris time at Noon. Both True Node and mean Nodes are given. Current: 4/01/2005 Obliquity ayanamsha: 23* 26.28' - Julian Date: 2453461.5 - Sidereal Time: 12 37 48' Lahiri Ayanamsha in computer programs: Current 4/1/2005 Birthtime: 00:00:00 - Chicago, Illinois - Zone 6 Standard Time 41 N 51 - 87 W 39. True Node - 365 days. Software (A.) Lahiri 23* 55: 41 - Tithi Saptami of Waning Moon - Midheaven 19* 10' 29'' Virgo - Vimshotarri Dasha: Moon 365 days KE JU ME ME 3/29/2005 Moon 360 days KE JU ME ME 3/30/2005 ****special note: A critical error happens if one just changes from calculated 365 Moon to 360 day tab without going first to log it as Moon calculation too. If not done then program will read Moon 360 days Ma Sa Ve Sa 3/28/2005 tab 365 days from here Ma Sa Ve Sa 3/29/2005 Software (A.) at 20 years 4/01/2025 Moon 365 days Ve Me Mo Ra 3/20/2025 Moon 360 days Ke Ju Me Me 3/30/2025 ACS Atlas used in program - backed up by JPL ___ Software (B.)

YIKES! My personal feeling is that Software (C.) with Gregorian Day is the most accurate. I say this because when I use my own birthchart with these calculations the Dasha resonate the closes to my personal experiences with this software's calculation. In fact most of my personal events can match dead on to how the Vimsottari Dasha play out as well as the Narayan Dasha system. However, saying that does not mean I have it all correct. And that is why if any others here with experience with different Calculations can put in there wise counsel and give advice on how one is to determine the best planetary system to work with charts and Dasha systems. It is quite mind boggling to say the least. Uttara p.s. can anyone tell me if the Jet Propulsion Laboratory (NASA) Algorithms for planetary positions by Dr. Myles Standish is available? And – what does everyone else use for their chart calculations? p.s.s please feel free to pass this email on to those you think have the mathematical knowledge and where withal if you are stumped. Any replies will be appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 18, 2005 Report Share Posted April 18, 2005 Dear Uttara, Unfortunately I haven't done any manual calculations for several years now (relying solely on my computer software - Goravani Jyotish and Parashara's light). Both these programmes are close enough in their dasa calculations to satisfy my needs. Certainly dasas can often be "out" due to several reasons, including incorrect T.O.B., however careful observation of events can usually rectify any discrepancy. It's perhaps not such a bad thing that such discrepancy's exist as it makes us more reliant on our own ability to discern and rectify a chart. Events will only manifest during appropriate planetary conditions...far better to put the effort into verifying such influences than to rely solely on computerised data which, as we know, varies depending on it's source.

Guest guest Posted April 18, 2005 Report Share Posted April 18, 2005 Dear Miss Wendy, I shall be much obliged if u let me have the contact i.e. where to buy Parashara's light programme Thanks for all your help in past and future . As per your advise I carry on with anusthan at the moment and today is Ramnavami. awaiting yr reply. regards pdk.
