Abstract
A dispersed Fourier transform spectrometer (dFTS) was used to measure the radial velocity of stellar targets. A mechanical-based metrology system intrinsically built into the dFTS instrument was enhanced with a laser-based optical metrology system. Precisions of the optical path difference within the instrument were brought from about 20 nm to 0.1 nm resulting in highly precise radial velocity measurements on the order of 1.5 m/s. Without the optical metrology system radial velocity measurements were only precise to about 300 m/s. The stability of the dFTS instrument was measured by calculating the zero-point radial velocity over the operational time of the instrument using a thorium-argon line-spectrum light source.

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 it
