बौधायन श्रौतसूत्रम् (कृष्ण यजुर्वेद तैत्तिरीय शाखा - सम्पूर्ण प्रश्न एवं श्रौत-याग कल्प सटीक)

क्थास्त्रयो... संवत्सराय ५
Yes, that '५' is a marginal line number!
Should we include it or omit it? It is printed on the line. We can transcribe:

Yes, "विपथौ"!

Let's check line 2 again: "ऋतूपर्यायं" vs "ऋतुपर्यायं":
Look at the u-matra under त in "ऋतुपर्यायं":
Wait, in "अथर्तुपशुभिर्यजत": look at "र्तु": it is त with repha and u-matra curving down-left.
In "ऋतुपर्यायं": look under 'त': it has a curve to the right: ू (dirgha)?
Wait, look really closely at "ऋतूपर्यायं":
It has a loop to the right and down, like ू (dirgha)!
Wait, why would it be ऋतूपर्यायं? In Vedic/Sanskrit compounds, sometimes rhythmic lengthening happens (e.g., ऋतूपर्यायम्). Or it could just be a font variant. Let's look: it really does look like ऋतूपर्या
