Rishi: Traditionally attributed within Soma-Pavamāna corpus; specific ascription for 9.112 varies by recension/Anukramaṇī (often treated as part of Pavamāna collections rather than a single personal rishi).
Devata: Soma Pavamāna (Indu), with refrain ‘for Indra’ (Indra as recipient/empowered by Soma).
Chandas: Not securely derivable from supplied extract alone; likely a common Pavamāna meter (often Jagatī/Triṣṭubh in Book 9), but requires syllable-count verification.
