The galactic plane region near
Bibliographic record
Abstract
\n We present new Canadian Galactic Plane Survey radio continuum and \\( \\lambda \\)21 cm\nH I line observations of NRAO 655 (G93.4+1.8), plus radio recombination\nline observations, and optical H\\( \\alpha \\)-line observations. The radio\nspectrum of NRAO 655 confirms its emission as thermal. From the \\( \\lambda \\)21 cm\nH I data we find an atomic hydrogen cavity associated with this\nobject at \\( v \\simeq -71.5 \\) km s\\( ^{-1} \\). The cavity\ncorresponds in position and size to the brightest radio continuum emission from\nNRAO 655. The corresponding kinematic distance is 8.8 kpc, placing NRAO 655\nin the Perseus Arm. NRAO 655's linear size is therefore 70 pc \\( \\times \\)\n130 pc. To confirm the \\( \\lambda \\)21 cm H I velocity we present\nthe first recombination line detection of NRAO 655 (H158\\( \\alpha \\) line,\n\\( v \\simeq -71 \\) km s\\( ^{-1} \\)), and the first observations\nof a molecular cloud coinciding with NRAO 655 (at \\( v \\simeq -72 \\)\nkm s\\( ^{-1} \\)). The first optical detection of \\( \\lambda \\)656 nm H\\( \\alpha \\)\nemission line features in NRAO 655 is also presented, and the H\\( \\alpha \\)\nemission line brightness is determined. We suggest that the eastward extension\nof this strongly asymmetric object originates in a champagne outflow, and we\nestimate its age. We show that a single early-type star cannot be responsible\nfor the outflow, whereas a group of later-type stars would suffice. A partial\nH I shell is seen adjacent to the brightest part of NRAO 655;\nwe suggest that it has been formed by dissociation of H\\( _{2} \\) in the molecular\ncloud. \n\t\n\n

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
