IX.9 IX. SAURA-SIDDHĀNTA — SOLAR ECLIPSE 203 The author gives 63,13,219, the difference, 27 parts, giving a difference of 2" in longitude being very small; for by neglecting a small fraction equal 1/7 in the divisor to make it a whole number, can give this difference. The readings here are extremely corrupt: Our explanation itself will show that the emendations we have made are necessary. We have read dvighanagaja as trighanaśata while TS give the correction trighanadaśa. The textual reading, carayamavasubhūtārṇavaguṇādhṛtibhakta is corrected by us as svarayamavasubhūtārṇavaguṇādhṛti-bhakte. But TS give the correction yamavasubhūtārṇavagu- ṇadhṛtibhiḥ. Here it is improper on their part to omit two letters cara though they require this omis- sion since in trighanagaja they have given daśafor gaja, instead of śata given by us. Nothing is gained by reading daśa instead of śata for gaja. Further, by omitting cara which is a corruption for svara, the number 7 in the unit's place is omitted by them, with the result that in the yuga an error of plus 30° and more is caused in Rāhu, while it is actually 46' 2" according to our correction. NP make the cor- rect emendation trighanaśataghne but emend cara to kara. We have corrected dahanaśabdāḥ as dahanarasa which fits the rule as shown. But TS content themselves with remarking that here the numbers of the kṣepa cannot be determined owing to the extreme corruption of the text. NP have made the emendation dahanaṣaṭ here, which too will serve the purpose. That the Head of Rāhu obtained by deducting what is got from 12 rāśis has been explained in dealing with the Paulīśa. We read sahati in the text as navati, since the difference of 90° between moon and Rāhu gives the maximum latitude, which is 270' according to the Saura, as also in all later Hindu Siddhāntas like the Āryabhaṭīya. Or we may read it as mahati, since the greatest difference, viz. 90° will give the greatest latitude, viz. 270'. But TS read it as sahita, and give something farfetched and unacceptable. NP emend sahati as timira, which neither accords with the lettering of the manuscript nor give the sense 90° required here. That the latitude is proportionate to the sine of (Moon ~ Rāhu) has already been explained in the context of the Romaka, and will also be shown below, in verse 25 of this chapter.

The mean longitude of the Sun minus 80° is called the Sun's (mean) anomaly. The mean Moon minus its apogee is its (mean) anomaly. Multiply the sine of the anomaly of the Sun by 14, and that of the Moon by 31. 8. Divide each by 360, and find their arcs. Put the Sun's arc in two places, for subsequent use. The arc of each is to be deducted from its mean longitude if
