TB 1.5.1 gives Rudra's nakshatra as the dual Bāhū 'the two arms' in place of Ārdrā, fitting the picture of the celestial deer (Orion): the two bright shoulder stars Betelgeuse + Bellatrix. Which two stars are meant is not stated in the text; Betelgeuse-Bellatrix is the common scholarly reading, and the mention of 'hunters' (mṛgayavaḥ) alongside is part of the same Orion tableau.
