DEVELOPMENT OF A HYBRID LASER-MASS SPECTROMETER WITH TWO INSTRUMENT ARMS: IRMPD AND HENDI COLD ION SPECTROSCOPIC EXPERIMENTS
Bibliographic record
Abstract
The [7.7] \\textit{Y} $^{2}\\Sigma^{+}$ - \\textit{X} $^{2}\\Pi_{\\textit{i}}$ transition of CuO was observed in emission from a Cu hollow cathode recorded with the FT-spectrometer associated with the McMath-Pierce Solar Telescope at Kitt Peak in 1994. In 1996, a rotational analysis of the (0,0) band of the \\textit{Y} - \\textit{X} transition was reported by O’Brien \\textit{et al}. In a recent analysis of the (0,0) and (1,1) bands of the [16.4] \\textit{A} $^{2}\\Sigma^{-}$ - \\textit{X} $^{2}\\Pi_{\\textit{i}}$ transition of CuO performed by the authors, improved centrifugal distortion constants for the \\textit{X} $^{2}\\Pi_{\\textit{i}}$ state were obtained. Line positions from the millimeter wave spectrum of CuO reported by Steimle \\textit{et al}. were successfully incorporated into the fit of the \\textit{A} – \\textit{X} transition, however, a fit including the line positions of the \\textit{Y} - \\textit{X} transition reported by O’Brien \\textit{et al}. showed small, yet significant, deviations in the residuals of the fit. In this study, the FTS data from 1994 was accessed from the FTP archive available from the National Solar Observatory website to investigate these deviations. The calibration of the data was verified to $\\pm$0.001 \\wn using Ne reference lines from Sansonetti \\textit{et al}. Using PGOPHER simulations and the improved rotational constants for the \\textit{X} $^{2}\\Pi_{\\textit{i}}$ ground state, over 1000 additional line positions belonging to the (0,0) band of the \\textit{Y} - \\textit{X} transition were identified in the FTS data. Several previously unidentified vibrational bands were also observed and rotationally analyzed using PGOPHER, specifically the (2,0), (2,1), (2,2), (2,3), (1,0), (1,1), (1,2), (1,3), (0,0), (0,1), and (0,2) bands. A comprehensive fit of the data containing more than 10,000 line positions has been conducted using PGOPHER. The fit successfully incorporated the millimeter wave data for the \\textit{X} $^{2}\\Pi_{\\textit{i}}$ state from Steimle \\textit{et al}. and the intracavity laser absorption data for the \\textit{A} - \\textit{X} state from the authors. Results of this analysis will be presented.

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.
