Appendix II, entitled Sphuțanirnaya-nirņīta-paryaya dayah, depicts, succinctly, in verse-form, the astronomical constants of the Sphuțanirņaya converted to the katapayadi notation, besides setting out two methods for correcting the bhagana-s (aeonary revolutions) of the planets, their apses and nodes.
The edition of the work is based on the two manuscripts noticed below:
A. Madras Mal. D. 339 H], being a paper transcript in Malayalam script prepared from a palmleaf manuscript in the same script. The codex contains about thirty works on astronomy, not hitherto correctly identified or catalogued. The transcript, which is accessioned under the general collective title Parahita-driksiddhaganitam and described in the Catalogue of Malayalam Mss. of the Govt. Oriental Mss. Library, Madras, under No. 339, has, lately been transferred and preserved in the Kerala University Or. Res. Inst. and Mss. Library, Trivandrum. In the transcript, the present text occurs on pages 28 (line 15) to 30 (line 17). The text contained here is practically correct.
B. No. 414-A (9) of the Kerala Univ. Res. Inst. and Mss. Library. The work, which had not been previously identified, occurs on folios 44 and 45 of this well-preserved palmleaf manuscript and has been catalogued in the Library, collectively with certain other works, under the title Pancabodha-ganitam. The text contained here is practically error-free.
Appendix III. Tantrasangraha-paryayaih Sphutanirna yoktabhagаnапауапаm. This tract explains how the bhagana-s (aeonary revolutions) of the planets as enunciated in the Sphutanirnaya could be derived from those enunciated in the Tantrasangraha of Nīlakaņțha Somayaji (A.D. 1443-1545), a predecessor of Acyuta in the discipline of astronomy. Three manuscripts of this tract, as noticed below, have been identified and used for its edition :
A. No. 414-A (10) of the Kerala Univ. Or. Res. Inst. and Mss. Library, a palmleaf manuscript in Malayalam script, described under Appendix II.
