352 PAÑCASIDDHĀNTIKĀ XVIII.60 चन्द्रादीनां 'द्वादश मनुरवितिथ्यष्टतिथि'संज्ञैः ॥ ५८ ॥ 58c-d. The setting and rising (mentioned above in verse 58a) is by 12°, 14°, 12°, 15°, 8° and 15° for the Moon etc. Note 1. This has to be taken with verse 58a. The degrees given here separately are according to the Vāsiṣṭha-Pauliśa, which do not instruct the correction due to the latitude of the planet or for even the latitude of place (ākṣa-valana). The result will therefore be very rough. Note 2. These degrees are necessarily arbitrary as mentioned already, and the correctness of the numbers cannot be verified in the absence of the original siddhāntas which are now lost. But we can guess the probable values as we are sure of the relative luminosities of the planets. The numbers seem to have been misplaced. They should be dvādaśa, tithi, manu, ravi, aṣṭa, tithi (12°, 15°, 14°, 12°, 8°, 15° for Moon etc.) All siddhāntas give 17° for Mars instead of 15°. The rest are nearly correctly given, according to one siddhānta or other. [कालभागानां क्षेत्रभागकरणम्] (त्रि) शतविनाडीगुणितै (रू) द (य) [वि] नाडीप्रमाणहृतैः । लब्धांशकप्रमाणादुदयोऽस्तं वा स्फुटं वाच्यम् ॥ ५९ ॥ Conversion of time-degrees into distance-degrees 59. Multiply the degrees by 300 and divide by the vināḍīs of oblique ascen- sional difference of the sign, rising at that moment, (near sunset or sunrise, as the case may be), and get the respective degrees. When the distance bet- ween the sun and planet is that much, the respective setting or rising takes place. Note 1. This work is what is known as the conversion of time-degrees (kālabhāga) into degrees of distance on the ecliptic (kṣetrabhāga). Since the rule has to apply commonly to Saura on the one hand and the Vāsiṣṭha-Pauliśa on the other, it has been placed last. Note 2. Since the positions of the Sun, Moon and planets are given only on the ecliptic, this con- version is necessary to measure distances. ज्ञसिताऽऽरेज्या (र्व्यू) नाः शशिनः प्रत्युत्तरं खरां (शुश्च) । ज्ञात्वैवं विक्षेपादादेशमनागतं कुर्यात् ॥ ६० ॥ 60. (The rising takes place in the east when) Mercury, Venus, Mars, Jupiter and Saturn are less in longitude than the Sun, and the Sun is less than the Moon in the opposite direction, (i.e., west). Making the computation according to the instruction given above using the latitude etc, the phenomenon should be predicted. 60a. A.B.C. र्ज्यकोर्नाः 59a. A. त्रिंशत; B. त्रिशति. B. विनाडी b.
