Hello,

Had come across an opensource library https://manpages.org/swetest to compute the planetary positions. Interestingly this allows using different Ayanamshas. Do any of you have an experience using this library? How's the accuracy? What are some lesser known yet highly effective features? What are some limitations? Any serious calculation issues, etc..?

Are there any other open-source libraries that you guys use to compute the position of the planets

Of course, these libraries are not a substitute for applications like Kala. But they would help in data analysis experiments.

Thanks!

As it uses the swiss ephemeris it should be accurate.

@ernst Thanks for confirming.

Will look to use it for experiments. Assuming it does not deter the Kala project's financial growth, can you let me know what open source tools are used for planetary position calculations?

@nikhil-ranka The only tool to use for calculating planetary positions and other basic astronomy things is the swiss ephemeris from Astro.com 

its free for personal use, if you make a product to sell it has a one time licensing fee of about 800.00, and that is CHEAP for what you get. It would costs tens of thousands to pay someone to program all the stuff that is easily available in the swiss ephemeris.
