Guest guest Posted June 6, 2005 Report Share Posted June 6, 2005 Dear Members, I have some questions regarding Jhora 7.02 (full 57 mb version) : Why is there a difference in arc seconds/minute between Jhora 7.02 and Swiss Ephemeris ? Using planetary positions on 1st of Jan 2005, 00:00 hr, GMT +00:00, Lahiri, as an example : Jhora = Sun 16:44:50.83 Swiss = Sun 16:44:28.6793 Jhora = Moon 15:22:12.37 Swiss = Moon 15:22:09.7656 Jhora = Mars 10:26:02.53 Swiss = Mars 10:25:29.0106 Jhora = Mercury 24:29:01.41 Swiss = Mercury 24:28:35.4791 Jhora = Jupiter 23:21:58.32 Swiss = Jupiter 23:21:46.2340 Jhora = Venus 25:11:12.33 Swiss = Venus 25:10:30.8806 Jhora = Saturn 01:00:07.95 Swiss = Saturn 01:00:19.9033 Correct me if I am wrong, both software is using exactly the same ephemeris file "sepl_18.se1" to generate these planetary positions. If that is the case, shouldn't the figures be exactly the same or at least the same after rounding off the arc second decimal places ? This is not an attempt to put Jhora in bad light, but a serious desire to find out why the difference in the figures. I use Jhora frequently and I am very grateful to Narasimha for not only releasing such a fine software free of charge but also uploading the full 57 mb version for the public to download. Thanks in advance to any reply to my above-mentioned queries. Best Wishes, Pushya Quote Link to comment Share on other sites More sharing options...
