The following is an outline of the various topics discussed in Jyotirmimamsa. • The necessity of revising the astronomical constants at regular intervals for correcting the parameters connected with astronomy • The meaning of
devatha prasada, which is manifested in the intuition of the astronomers, as a prerequisite for obtaining the accurate values and the correct approach in the astronomy • The experimental determinations of the astronomical constants and the tools used for these determinations • The need and the importance of conducting experiments in astronomical studies • Significance of the astronomical books and the base of collecting data from those books • Application of corrections, called
bija correction, for the astronomical figures • The corrections known as the
Bhatta correction • Justification of the changes made by the astronomer Lallacharya in his book
Sishyaddhi vruddhi tantra • Reasons for difference in the mean planets though the revolutions are identical • Vedic authority for inference as a means to derive the number of planetary revolutions • Different systems of astronomy • The numbers of planetary revolutions enunciated by Sripati and Brahmagupta • The numbers of revolutions of planets, apogees and nodes, number of days, in a
Kalpa (in astronomy, a period of 14×72×4320000 years) • Zero points of the planets at the commencement of
Kali Yuga, corrections to planetary revolutions • Relative accuracy of the different astronomical systems • Mean planets according to the Sunrise system of
Aryabhatiya, mean planets, Moon's apogee and Moon's node according to
Siddhantasekhara • Application of the values in the astronomical calculations, astronomical corrections given on the bases of the eclipses • Eclipses observed by Parameswaracharya • Method of corrections given by other astronomers • Demonstration of the validity of those corrections through eclipses, precision of equinoxes, calculation and the correction, correction of the periphery of the manda epicycle, discussion on the precision of the equinoxes, corrections due to the precession of the equinoxes • Sine table for
praanakalaantara, sine table for the ascensional differences • Derivation of the 36 Rsines • Graphic proof for the relation of the sides and hypotenuse • Reason for the reduction of the minutes of arc of the planetary orbital to the visible celestial sphere ==See also==
