The Universal System of Astronomy, Part Two

Siṃ. Vi. 2 original: Siṃ. Vi.; abbreviation for a title such as Siddhānta Vijaya. He who knows this nature again and again, knows the peg original: kīlaka; a technical term for the gnomon or its fixed point and the performer. This type [of knowledge] belongs to the three sets of eight likely referring to 24 units or divisions known as the Great Rudra of Knowledge original: jñānamahārudra; potentially the name of this specific computational method or text.

Regarding the peg... by the gnomon original: śaṅku; a vertical rod used to measure shadows, the result is obtained. By that result of the Great Rudra of Knowledge, the fruit is not [reached]. Here, if the result is less than the surface of the peg, it is for the purpose of the remainder of the directions.

From the shadow... the north shadow... the planets original: graha... knowledge of the south original: dakṣiṇa. Otherwise, when the result is diminished...

By joining the directions... from the south, the knowledge of the north original: uttara is [gained]. [8] By these nine verses original: śloka, the calculation of time by the Great Rudra... [5]... The declination original: krānti; the sun’s distance north or south of the celestial equator divided by the hypotenuse original: karṇa; the diagonal line from the gnomon tip to the shadow tip is subtracted from the difference. [9]

Having established the radius original: trijyā; literally "three-jivas," the standard radius of 3438 minutes used in Indian trigonometry for the purpose of the Great Rudra... the declination is placed. [10] Multiplied by the forms... by the radius...

Multiplied by the qualities... with the sun to be determined... the parts of the difference from the radius... the day... Great Rudra. [2 m 7, 11] Deprived of the calculation equal to the observation... declared from the sky...

...the equinoctial hypotenuse original: palakarṇa; the hypotenuse of the midday shadow at the equinox. In the hypotenuse, twelve is the base original: dvādaśa koṭi; standard Indian gnomons are exactly 12 digits high, forming the "base" of the calculation... what is the base in the hypotenuse... the sine of the declination original: krānti jyā...
