ORCHESTRATING OBSERVATORY, LABORATORY, AND FIELD: JULES JANSSEN, THE SPECTROSCOPE, AND TRAVEL
Bibliographic record
Abstract
Abstract title SUMMARY /title In the last third of the nineteenth century, astrospectroscopy played a prominent part in orchestrating transitions undergone by three sites of knowledge production: the observatory, the laboratory, and the field expedition. Early astrophysicists carved out for themselves a specific social space by adopting experimental techniques and practices stemming out of the laboratory, and adapting them to the observatory and the field traditions, and more generally by easing the back-and-forth transfer of practices from one site to another. Taking advantage of the circulation culture constitutive of the observatory sciences, the 'new astronomy' provides a useful standpoint from which historians can examine anew the 'institutional revolution' in the laboratory sciences in chemistry, physics, and physiology. To exemplify this process, the French reception of Bunsen and Kirchhoff's work and Jules Janssen's trip to Italy in 1862-1863 are here discussed.

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.
