फाल्गुन्योर् भाद्रपदयोस् तथैवाषाढयोर् द्वयोः / विशाखाश्विनिसौम्यानाम् योगतारोत्तरा स्मृता //
16. Of the two Phalgunis, the two Bhadrapadas, and likewise the two Ashadhas, of Viçakha, Açvini, and Mrgaçirsha (saumya), the junction-star (yogatara) is stated to be the northern (uttara): — E. Burgess (1860)

Burgess: the text's position gives 'a longitude... of one member of the group [γ Pegasi], and a latitude which is that of the other [α Andromedae]'; 'There can be no doubt that the two stars recognized as composing the asterism are γ Pegasi and α Andromedae, but there has evidently been a blundering confusion of the two'. Modern lists usually take γ Pegasi.

uttarabhādrapadā-nakṣatraṃ dvitāraṃ padaka-saṃsthānaṃ pañca-catvāriṃśan-muhūrta-yogaṃ māṃsāhāram aryamādaivataṃ dhyānadrāhyāyaṇīyaṃ gotreṇa/
Literal rendering: 'The Uttarabhādrapadā asterism has two stars, is padaka-shaped, has a forty-five-muhūrta conjunction, flesh for its food, Aryamā for its deity, Dhyānadrāhyāyaṇīya by gotra.' — Literal rendering by the compiler

TWO stars, padaka-shaped, deity Aryamā, gotra Dhyānadrāhyāyaṇīya. The two-star count supports the pair γ Pegasi + α Andromedae that Burgess said the text confuses — evidence the confusion is his sources', not the tradition's. NOTE the deity Aryamā where the Brahmanical lists have Ahirbudhnya, duplicating Uttaraphalgunī's deity.

Devanagari transcribed by the compiler from the page FACSIMILE of the Ray edition (Calcutta 1899), scan leaf n216 = printed p. 114–115: https://archive.org/download/in.ernet.dli.2015.292705/page/n216.jpg . The archive.org OCR of this volume is unusable for Devanagari, so no verse here is taken from the OCR text; every figure was re-read at full scan resolution and cross-checked against a second independent scan of the same edition (https://archive.org/download/siddhantadarpanachandrashekarsimha1897_252_Z/page/n217.jpg). Round brackets and the figures in them are the PRINTED EDITION'S own: (n) is the serial number of the asterism/star and the figure following it is the edition's decoding of the bhūtasaṅkhyā word-numeral that precedes it. These are the two printed segments of the dhruva list (vv. 2–6) and the śara list (vv. 7–10) that carry this asterism's own figures; the complete verses are given under db_id 'yogatara-catalog'.

'…(26) 338 00…' and '…(26) 28 00…' — the polar longitude of asterism no. 26 is 338°00' and its polar latitude 28°00', north. — Literal rendering by the compiler

SIDDHĀNTA DARPAṆA XII (Sāmanta, 1869): dhruva (polar longitude) 338°00', śara (polar latitude) 28°00' north. The direction comes from XII.11, which makes the śara southern for the asterisms numbered 4, 5, 6, 9, 13, 14, 16–21 and 24 and northern for all the rest; XII.12–13 give the asterism 2 star(s). TRUE VALUES for 1870 CE, reduced to Sāmanta's OWN sidereal zero (his Citrā = 179°, i.e. Spica; implied ayanāṃśa 22°12'), as polar longitude / polar latitude: α And 338°16' / 28°11'; γ Peg 339°35' / 13°45'. VAṬEŚVARA-SIDDHĀNTA VIII.2.1–2 (904 CE) puts the same junction star at Mīna (Pisces) 7° (= 337°00' measured from the sidereal origin) with a śara of 26°00' north (VIII.2.5–6, direction by VIII.2.8). ★ DECISIVE FOR THE DISPUTED IDENTIFICATION. Sāmanta's 338° / 28° N matches α Andromedae (Alpheratz: 338°16' / 28°11') to 16' and 11'. γ Pegasi, the other candidate, has a polar latitude of only 13°45' — more than 14° away from the stated value. Vaṭeśvara's older 337° / 26° N points the same way. The junction star of Uttara-Bhādrapadā in both texts is therefore α Andromedae, not γ Pegasi.

नग[७]त्रिंशैः[३०] … मीनेऽश्विन्यादीनि द्युचरैर्योगं व्रजन्ति

This is the printed segment of the continuous dhruvaka list (VIII.2.1–2) that carries this star's own figure; the star's kṣepa is item no. 27 of the unbroken numeral run of VIII.2.5–6, which cannot be split, so the whole passage is also given verbatim under db_id 'yogatara-catalog'. Devanagari transcribed by the compiler from the page FACSIMILE of K. S. Shukla's INSA edition of the Sanskrit text, scan leaf n317 = printed p. 293: https://archive.org/download/VatesvaraSiddhantaSanskritText/page/n317.jpg . The archive.org OCR is unusable for Devanagari. The SQUARE brackets and the figures inside them are the EDITION'S own decoding of the bhūtasaṅkhyā word-numerals, reproduced here so that no numeral is silently converted. Shukla's English translation and notes are in copyright: they are neither quoted nor relied on here — only the constituted mūla text and the edition's numeric glosses.

Vaṭeśvara names no asterism individually in these verses: he gives, sign by sign, the degrees at which the junction stars stand. This star falls at Mīna (Pisces) 7°, with polar latitude 26°00' north. — Literal rendering by the compiler

VAṬEŚVARA-SIDDHĀNTA VIII.2 (904 CE) gives the junction star's dhruvaka (polar longitude) as Mīna (Pisces) 7° — Vaṭeśvara states the dhruvakas as degrees WITHIN each zodiacal sign, not as absolute longitudes, so this is 337°00' from the sidereal origin — and its kṣepa (polar latitude, VIII.2.5–6) as 26°00', north by the rule of VIII.2.8 (a verse the edition notes is identical with Brahmagupta's Khaṇḍakhādyaka I.9.13). TRUE VALUES for 904 CE reduced to Vaṭeśvara's own sidereal zero (his Citrā = 3° of Libra = 183°), as polar longitude / polar latitude: α And 342°32' / 28°07'; γ Peg 343°43' / 13°42'. For comparison Sāmanta (1869) gives 338°00' / 28°00' north. Vaṭeśvara's list is essentially the inherited Sūrya-Siddhānta/Brahmagupta set: it is a fourth independent witness to those values rather than a fresh observation.

Chinese Buddhist witnesses · Xiuyao jing 759 CE (revised recension 764 CE); Modengqie jing (T1300) attributed to Zhu Lüyan and Zhi Qian, 230 CE; Shetoujian jing (T1301) Dharmarakṣa, c. 307 CE
璧圖。壁二星,形如立竿,尼陀羅神也,姓瞿摩多羅,食大麥飯酥乳。

Verbatim parallels from the two earlier Chinese versions of the same Śārdūlakarṇāvadāna material, and the Tang commentator's note on the Chinese star-count: 摩登伽經 (Mātaṅga-sūtra) T21n1300, T21.0405a22: 「壁宿二星,形如人步,一日一夜及月而行,以肉祭之,屬於善神,姓陀闍延。」 | 舍頭諫太子二十八宿經 T21n1301, T21.0415c28: 「北賢迹宿,有二要星,相遠對立,行三十五須臾而侍從矣,以牛肉為食,主於米天,姓不。」 | Yang Jingfeng's interlinear note in T21n1299 at T21.0390b23: 「景風曰:中國天文,壁二星,主圖書祕法,北方之宿也」

Xiuyao jing: "Chart of Bi. Bi has two stars; its form is like an upright pole. Its deity is Nidrā/Indra(?) (尼陀羅); its clan is Gomātra (瞿摩多羅); its food is barley-rice, butter and milk." — Modengqie jing (T1300, c. 230 CE): "The Bi asterism has two stars, its form like a man's step; a day and a night it travels with the moon; flesh is used in its offering; it belongs to the Good deity; its clan is Dhvajāyana (陀闍延)." — Shetoujian jing (T1301, c. 307 CE): "The asterism Northern-Worthy's-Footprint has two principal stars standing far apart and opposite; it travels thirty-five [read forty-five] muhūrta in attendance; ox-flesh is its food; the deva of Rice presides; its clan-name is [defective]." — Literal rendering by the compiler

Chinese lunar lodge (xiu) 壁 Bi; T1301 renders the name semantically as 北賢迹 ('Northern Worthy's Footprint'). TWO stars in all three witnesses, matching dvitāraṃ padaka-saṃsthānam and supporting the pair γ Pegasi + α Andromedae that Burgess thought the Sūrya Siddhānta confused. T1301's 相遠對立 again describes a widely separated pair. The 45-muhūrta value is confirmed by T1300's summary list of the six long asterisms (畢井氐翼斗壁) although T1301's body misprints 三十五. The deity is unstable across all witnesses — T1299 尼陀羅, T1300 善神, T1301 主於米天 — matching the instability in the Sanskrit tradition itself, where the Śārdūlakarṇāvadāna gives Aryamā against the Brahmanical Ahirbudhnya.
