Erratum: “Simultaneous X-Ray and Infrared Observations of Sagittarius A*'s Variability” (2019, ApJ, 871, 161)
Bibliographic record
Abstract
In the published article, we presented Chandra X-ray light curves that were barycenter corrected using an incorrect right ascension (R.A. = 17° .76)for Sgr A * .Here we correct Sgr A * ʼs position to the known radio position (R.A., decl.= 17:45:40.0409,-29:00:28.118;Reid & Brunthaler 2004), using R.A. = 266° .42 and recompute the barycenter correction and cross-correlation analysis.This changes the time lag between the X-ray and IR emission by 2.5-5.8minutes, still within our 68% error bars.The corrected time lags are reported here in Table 2 and Figure 4.These changes do not affect the scientific conclusions in the published article.

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.
