The Low-Resolution DRAO Survey of H [CSC]i[/CSC] Emission from the Galactic Plane
Bibliographic record
Abstract
A survey of H I line emission in the Galactic plane from Galactic longitude l = 72 2 to 149 0, and latitude b = -5 4 to 7 2, has been made using the 26-m Telescope at the Dominion Radio Astrophysical Observatory. Spectra were observed at 0 2 intervals of longitude and latitude, providing a survey which is fully sampled in the spatial domain. A detailed study of the antenna characteristics of the telescope allowed the correction of the spectra for stray radiation. The spectral resolution is 1.32 km s -1 , and the LSR velocity range is -260 to 161 km s -1 . The final spectra have an estimated T b scaling accuracy of 1% and an estimated rms noise in one channel (0.8245 km s -1 ) of 0.25 K. A region of suspected strong H I self-absorption at l ∼ 92°, b ∼ 3°, has been identified. Comparison with spectra from the Leiden/Dwingeloo Survey is used to estimate the overall accuracy of the stray radiation corrections. This comparison also shows that a small percentage (∼1%) of the spectra in the latter survey suffer from calibration errors exceeding 10%. A table of positions of the more discordant spectra is given.

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.
