Surya Siddhanta
यद् ग्राह्यम् अधिके तस्मिन् सकलम् न्यूनम् अन्यथा । योगार्धाद् अधिके न स्याद् विक्षेपे ग्राससम्भवः॥
If this quantity should be greater than the diameter of the disc which is to be eclipsed, the eclipse will be a total one, otherwise it will be partial. But if the Moon's latitude be greater than half the sum (mentioned in the preceding Śloka) there cannot be an eclipse.
english translation
