[Guest guest]

Hello All,Sreenadh ji, you are always so helpful.I searched the swiss ephemeris and tried to compile a few demos. But it didn't compile. May be some multi OS settings have created lot of dependencies!!!

Finally I got an open source application, MHORA. This is quite wonderful, and I am still juggling to make out my project deliverables. Though no help files make life hell!!! JHORA, as suggested, is quite good application, but an app w/o source code is as good as rock.

I found this quite ironic factor in Indian academia, of making more than 10000 astrology software and each with many unique qualities, but they are all closed source. What good they serve to anyone, I wonder least if they make any money?

Just imagine, what would have happened if our RISHIs would have made all slokas and mantras of sanskrit in some million byte encryption, impossible to decipher in universe lifespan. What would have happened to KNOWLEDGE itself? Count the total modern age recede by thosands of years atleast!!!

These softwares are mantras and slokas of KALIYUGA, and we need to dispense the knowledge, as Bharat should be known for.My project on astrology computing model is over, but I vow to make at least one complete open source project, MHORA in this case, with appropriate documentation and updated SVN.

I again appeal to all Scholars here, please make your work open source, take credit but let not your research die.Thanks & Regards,Prabhat Kumar SinghKolkata.phone  +91-9681857057

Dear Prabhat ji,   You are right.

I would love to know any method if I could generate ephemeris table using some sort of programming//  If you are looking for the most accurate values then better to depend on Swiss ephemeris for tropical planetary longitudes. You can visit http://www.astro.com/swisseph/swephinfo_e.htm?lang=e The provide API and tools to calculate ACCURATE  Tropical planetary longitudes. You can write your own program to use this API/library and (thus save yourself from extensive programming) then add the True Ayanamsa value to it to get the Sidereal (Nirayana) planetary position based on Surya Siddhantic True Ayanamsa. Instead if you depend on Javascript of C++ programs to derive planetary longitudes then, things might be simple and self dependent but the derived longitudes may not be

accurate enough. By the way, JHora uses this Swiss emphemeris itself. But since you are a programmer better to download the dlls etc provided by astro.com, license it (GPL or Swiss Ephemeris professional license) and  start programming utilizing the same within your program.

Hi,Dear Sreenadh Ji, many thanks for your clear explanations.I would prefer option 3 for the same, because, i think, this would be most accurate than other 2 methods. CORRECT?

I am basically duing a  project in computer modeling, and vedic astrology is fantastic.

I would love to know any method if I could generate ephemeris table using some sort of programming(javascript, C++ or matlab). This would free me from relying on pre-generated tables for finding Zodiac positions of planets.

Any one in this group, if knows about any such resource, please provide a direction. I did my research and found following 2 JS calculators. They are amazing! though not based on " True ayanamsha " .

Many many thanks!Prabhat Kumar SinghKolkata.

Dear Prabhat ji,

//the next obvious question which comes to my mind for what ephemeris table to use with true ayanamsha. And to my limited knowledge, I suppose

we would have to calculate that for true ayanamsha, because others won't be applicable to this.//  You are absolutely right. But the answer for the same as of now is -

 * There is no ephemeris currently available that provides all planetary longitudes based on True Ayanamsa (i.e. Surya Siddhantic Ayanamsa as clarified by Chandra Hari)

  But many work arounds are possible, such as -  1) Use any Lahari/Chitrapaksha based ephemeris and SUBTRACT 44 min from the availed planetary

longitudes (Or use ADD 44 min to the Lahari Ayanamsa during calculations)  2) Use a program like JHora and set the Ayanamsa to be used as Chandahari Ayanamsa; OR Use Lahari ayanamsa and set the program to add 44 min to Lahari ayanamsa (so that we get a value closer to True Ayanamsa; this is perfectly possible with JHora). In JHora if we set Ayanamsa as Chandrahari Ayanamsa OR if we set ayanamsa as Lahari+44 then what we get is planetary longitudes as per True Ayanamsa (or at least values very near to it, we can say).

  3) Use any ephemeris that provides planetary longitudes based on no ayanamsa (Tropical Chart/Western style) and then ADD the True Ayanamsa to the availed planetary

longitudes so as to get the True Ayanamsa based planetary position.  Try any work around choice that you find easy, comfortable and simple to use for you.

//Could you shed some light how you calculate planet positions using true ayanamsha and w/o using ephemeris based on other ayanamshas?//Hope I have answered this question above.

No. Because when we use Yuga numbers and system for calculation, that inherently means that we are depending on average speed, base year, degrees etc for calculation and this free us from considering leap years etc. Experiment with the formula and results it produce (you can compare with Lahari or Chitrapaksha Ayanamsa) to verify

the accuracy of the formula.  Please note that -* 8586  is a Yuga number (connected with average speed of planets as well)* 71.55 could be the human heart beat. (Bio rhythm which correlates with circadian rhythm)

Dear Prabhat ji,//I searched the swiss ephemeris and tried to compile a few demos. But it didn't compile. May be some multi OS settings have created lot of dependencies!!!// I think astro.com provides some developer guidelines also in their site, please check it out. Since many people implemented/used the same (scholars such as PVR ji, Ash ji, Sarajit Poddar etc - who are members of AIA group as well), some of them might be possibly guide/help you as well - if you contact them. MHora (Mudgala Hora) is a software written by Ajit Krishnan

ji. (http://www.mudgala.com/mhora/index.html) Possibly it was an effort create/complete a software in line with JHora. But as someone puts it, the effort didn't got further since when the code grew it became unmanageable and the developer dropped the project where it was and didn't continue the development further. By the way, 'Mudgala' is the name of an ancient indian sage. May be there was great class/quality of coding difference when the authors of JHora and MHora are considered. PVR is a rock solid programmer with excellent in manageable C++ coding it seems, while MHora was possibly an effort using DotNet libraries. The

versatility of features provided by JHora and the limitted features of MHora also explains it I think. I don't think PVR ji will make JHora opensource, and it is all his freedom and I don't even dare to ask him to do so, because he had bestowed much to me and the astrological community by providing the software to us all as freeware itself. But if ever he decides to make it opensource I would be well pleased and will feel happier. Now coming to MHora, I agree with you and you are right, it could be the starting point of creating an excellent OPENSOURCE astrology software.//My project on astrology computing model is over, but I vow to make at least one complete open source project, MHORA in this case, with appropriate documentation and updated SVN.// All my best wishes to such an effort. And if so, I think in result Ajit Krishnan ji will stand as a greater contributor to the cause of free opensource astrology software compared to JHora and PVR ji, since it is he who started it (by making the MHora source open). And ofcourse your contribution to the same also would be remembered and valued much. And if it continues one day MHora may even bypass JHora in its versatility I hope (due to further support from opensource community).//

These softwares are mantras and slokas of KALIYUGA, and we need to dispense the knowledge, as Bharat should be known for.// That is a beautiful statement and I agree with you. (but at the same time also foresee that, if apps like JHora is made opensource there would be appearing people with commercial interest trying to make money out of it, by extending it and then trying to sell commercial versions of the same).//I again appeal to all Scholars here, please make your work open source, take credit but let not your research die.// Well said!
