Detection of Methanol Maser Flares Near 19.9 and 20.9 GHz toward the Massive Source of Active Star Formation G358.931-0.030
Bibliographic record
Abstract
We have investigated the methanol CH 3 OH lines at frequencies of 19.967 GHz [2 1 -3 0 E( v t = 0) transition] and 20.971 GHz [10 1 - 11 2 E + ( v t = 1) transition] toward the massive region of active star formation G358.931-0.030 with the RT-22 (Simeiz) and RT-26 (HartRAO) radio telescopes. Two new flares have been detected. One of the flares (at 20.971 GHz) is extremely powerful in the frequency range 192-26 GHz. We present our monitoring of the flaring events detected at 19.967 and 20.971 GHz. The time dependence of the flare amplitude reflects the complex structure of the maser emission regions. The velocity structure of the flares is considered.

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.
