‘(15') If the DIŠ.U₄ of depth exceeds the elongation and the ṣiliptu-coefficient and the 2 for the disk you subtract the elongation and the ṣiliptu-coefficient and the 2 for the disk (16') from it. You call it GI₆.’

‘(9) (The amount) by which the position of Sin and the position of Šamaš exceed 10 (UŠ) of the zodiacal sign you multiply by (0;0),8. You add it with the corresponding ṣiliptu-coefficient for ‘height and depth’ if it is increasing, subtract if it is decreasing. You accumulate (them) together, you compute half of it, and you multiply it by the DIŠ.U₄ of height and depth which you had put down.’
