	Shylaja proposes the identification of "Turangana" with θ Psc or ι Psc.		Shylaja proposes the identification of "Turangana" with θ Psc or ι Psc. She checked another manuscript with solved examples. It gives the precession correction as 18 degrees for 1620 CE. So without bothering about the errors in ''dhruvaka'' and ''viksepa'', if she simply adds the precession correction it fits with theta Piscium.

			However, the text seems to be erroneous, as it gives the difference in coordinates (which does not depend on precession) with errors of 6° to 10°. This lets us doubt the reliability of this text.

	Since the Greek period in the ~~forth~~ century CE, Indian astral science used not only the older (Vedic) division of the observable "path of the moon" into 27 nakṣatras, but adopted also the Graeco-Roman division into twelve equal sections called Rāśi (राशिः), ~~equalling~~ the traditional zodiacal signs. A rāśi (राशिः) or zodiacal sign is a section of 30° alongside the ecliptic. Since (Greek) antiquity, ecliptic longitudes are typically not counted from one to 359, but are given as "zodiacal sign ''xy''" or "rāśi ''xy''", where 0 ≤ ''xy'' ≤ 30.
