First detection of NH<sub>3</sub> ($\mathsf{1_0 \rightarrow 0_0}$) from a low mass cloud core
Bibliographic record
Abstract
Odin has successfully observed the molecular core Oph A in the 572.5 GHz rotational ground state line of ammonia, NH 3 (J K = 1 0 0 0 ). The interpretation of this result makes use of complementary molecular line data obtained from the ground (C 17 O and CH 3 OH) as part of the Odin preparatory work. Comparison of these observations with theoretical model calculations of line excitation and transfer yields a quite ordinary abundance of methanol, X(CH 3 OH) = 3 10 -9 . Unless NH 3 is not entirely segregated from C 17 O and CH 3 OH, ammonia is found to be significantly underabundant with respect to typical dense core values, viz. X(NH 3 ) = 8 10 -10 .

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
