Rishi: Traditionally ascribed within the Vājasaneyin transmission to the ritual lineage (often treated as Yājñavalkya/ācārya-tradition rather than a single ṛṣi for such formulas).
Devata: Agni
Chandas: Tr̥ṣṭubh-like cadence (as transmitted; metrical exactness varies with Saṃhitā accent and sandhi).
