Identifying Sidereal Zodiac

[ABer]

Hi there - is there a way to identify which ayanamsa is being used? There is ayaname(), which identifies the name of the specific variation (Lahiri, Fagan/Bradley etc) to use in a string, but not the number in the list.

Thanks. Ed

command(FUNCTION, 11, h, 0)
It was missing from the help, it returns sidereal setting for horoscope number h.

Thanks Jean - much appreciated. Ed

Hi Jean - another question! is there a function to return the value of the ayanamsa in degrees? Thanks. Ed

[Jean]

No there isn't. I searched the SE code but couldn't find it, it should be in there but where.. Maybe there's a table online somewhere?

[Jean]

maybe you could make a table with a small script calculating all ayanamsha's?

Hi Jean - is there a command or function for using calcplanet() in tropical mode if the horoscope is sidereal. I think what I will need to do is calculate the tropical position of the sun, and then subtract the sidereal position of the sun. The difference is the ayanamsa.

Thanks. Ed

Done!

You just need to calculate a new chart with calculatesid(), but make the final variable trop = 0.

char trop = 0;

calculatesid(1, julianDay, geoLong, geoLat, -2, trop);

real tropPlanets[PLANETS];

getplanets(1, tropPlanets);

Subtracting the sidereal position of the Sun from the tropical position given by this calculation gives the ayanamsa.

Great you found it Ed.

Thanks Jean - this just demonstrates how flexible Astrobasic can be. Amazing! Ed
