INTRODUCTION


concluding note, the author of the tract goes on to mention how the said khanda-dhruva-s had been derived and indicates their comparative accuracy. Possibly, the author of this tract, too, is the same Puradahanapura-dvija, author of Appendix IV.

 The edition is based on a single manuscript of the work, being No. Jy. 568 (O) of the Govt. Sanskrit College Library, Tripunithura, described under Appendix I. The present unidentified and uncatalogued work occurs on folios 26b-27a of the manuscript. The text as preserved herein is pure.

 Appendix VI, being Sphutanirnayadharitaḥ Khandadhruvāh chooses Kali 17,97,000 as the zero date and gives computed results for the True Positions of the planets and the Moon's apsis and node, correct to the fifths ( L'). No author is mentioned in the work but, possibly, it is the same as Puradahanapura-dvija mentioned under Appendix IV above.

 Appendix VII. Sphutanirnayanitah Khandadhruvaḥ. Here is another set of results for the True Positions of the planets etc. correct to the seconds for the zero date 17,97,000, the derivation of which deserves to be verified in view of the differences found herein from those in Appendix VI.
