I was wondering if there is a critical edition of the Sūrya-siddhānta. I could not find one. However, there is something very close to one, although it is not called a critical edition. It is Kripa Shankar Shukla's edition, The Sūrya-siddhānta with the Commentary of Paramesvara. Lucknow University: Department of Mathematics and Astronomy, 1957. For the text of the Sūrya-siddhānta, he gives full variant readings from manuscripts of the text as commented on by Mallikārjuna Sūri (1178 CE), Yallaya (1472 CE), and Rāmakṛṣṇa Ārādhya (1472 CE), besides from the printed edition of Raṅganātha's commentary edited by Jīvānanda Vidyāsāgara. He says that he also consulted the commentaries by Bhūdhara (1572 CE) and Tamma Yajvā (1599 CE) for deciding between certain readings. Of course, the text is based on the commentary by Parameśvara (1432 CE), which predates the commonly used commentary by Raṅganātha (1603 CE) by nearly two centuries. When he has chosen a reading different from Parameśvara's, he cites Parameśvara's reading as mū. pustake, for mūla-pustake.

 

I did not find a digital copy of Shukla's edition online, but I have scanned the photocopy I made of it. Happy to send it to anyone who wants it. Perhaps someone who knows how can upload it to the web.

Best regards,
