Ayanamsas - Fagan/Bradley

There seems to be an interesting discussion of ayanamsas going on,

specifically Chandra Hari and Lahiri. In light of that, I have

uploaded a file to the Files section that pertains to the

determination of the Synetic Vernal Point aka the Fagan/Bradley

ayanamsa.

The file "Fagan-Bradley.Zip" contains a Word document of an article

that Donald Bradley wrote for American Astrology magazine in August

1964 under his pen name of Garth Allen. It clearly describes Cyril

Fagan's refinement of the Lahiri ayanamsa and Bradleys later refinment

of that value. It is a fascinating (if opinionated) article and has, I

feel, great historical value, in as much as it appears to be the only

ayanamsa among many that has been determined statistically against

hundreds of mudane events.

What I find especially interesting is that, for J2000, the

Fagan/Bradley value is 24d 44' 11.72" and Chandra Hari's value is 24d

35' 08.79". Only 9 minutes difference.

For JHora users, I believe the Fagan/Bradley calculation is in error.

The program uses an offset from Lahiri of 53' 30" while the correct

value is for 1 Jan 1900 is 53'00" as follows:

1900.1.1 : Lahiri: 22°27'55.19"

Fagan : 23°20'55.15"

Difference: 0°52'59.96" (= 53' 00")

I have written Narhashima P.V.R. Rao twice about this asking for

clarification but he appears to be very busy writting his book and

hasn't had time to reply.

So, if anyone is using Fagan/Bradley, select "Custom (user defined)"

and put in 50' 00" more than Lahiri.
