Methods are described in the publication.-- Folder frog_data: This folder contains the frequency resolved optical gating data for the 162 nm nanopillar diameter coating. Reference data for the incoming femtosecond laser pulses and the incoming laser pulses transmitted through the uncoated substrate only are also provided.The variables in the files are: wavelength_nm: wavelength axis for frequency resolved optical gating spectrogram in nanometers. delay_fs: delay axis for the frequency resolved optical gating spectrogram in femtoseconds. spectrogram: the raw frequency resolved optical gating spectrogram in arbitrary units.Folder white_light_data: This folder contains the raw white light interferometer data. Folders are named according to the nanopillar diameter of the examined compressor coating. For each coating, reference data of the empty interferometer, and reference data of the substrate in one interferometer arm (double pass) is also provided.The variables in the files are: wavelength: wavelength axis for the recorded spectral intensities in nanometers. background: Spectral intensity after the interferometer with both interferometer arms blocked in arbitrary units. A: Spectral intensity after the interferometer with sample arm blocked in arbitrary units. B: Spectral intensity after the interferometer with reference arm blocked in arbitrary units. AB: Spectral intensity after the interferometer in arbitrary units. wavelengthGD: wavelength axis for the calculated group delay in nanometers. frequencyGD: frequency axis for the calculated group delay in petahertz. GDnm: calculated group delay in femtoseconds (plot versus wavelengthGD). GDPHz: calculated group delay in femtoseconds (plot versus frequencyGD).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
