Shodasamsa (D16) in Vedic astrology

Shodasamsa (D16) is a divisional chart that splits each sign into 16 parts of about 1.88°. Each part is given a sign, so the planets fall into a new chart. The API lists its use as: vehicles and comforts. POST /v1/chart/D16 returns the sign and house of the ascendant and each planet in it.

Shodasamsa: how the API computes it

The shodasamsa, D16, splits each sign into 16 parts of about 1.88 degrees. Each of those small parts maps to a sign. Its signifies field reads vehicles and comforts, the classical use of this chart. It is the chart to check when a user asks about cars, travel or the ease of everyday life.

POST /v1/chart/D16 returns the ascendant (rising sign) and every planet with the sign and the house in this chart. They are counted by VG-02 and VG-03. At under two degrees per part, the parts are very small.

A planet only needs to move a little to change part. The ascendant moves a degree in about four minutes. So the D16 ascendant can change with a small error in the birth time.

Your app may only know the time to the nearest hour. Then it is better to leave out the charts with small parts, such as this one. Or show them with a note about the accuracy.

How we check the numbers

Every value here starts from planet positions worked out from NASA JPL planet data (DE440). We test them against NASA JPL Horizons, NASA's planet position service. On 25,571 positions from 1850 to 2149, the Sun and planets agree within 0.001 arc seconds. The Moon agrees within 0.011. On 2,000 random birth charts, the rising sign agrees with Swiss Ephemeris within 0.004 arc seconds. An arc second is 1/3,600 of a degree. A practicing astrologer reviews the rules behind these answers. See how we test.
