Two independent calibration pipelines for the same instrument: an Ocean
Optics USB4000 spectrometer, at the Institute of Physics, University of
São Paulo. wavelength-calibration/ states its end application
directly in its own header: spectral characterization of a cold
dielectric-barrier-discharge (DBD) plasma. fel-lamp-calibration/
calibrates the same instrument's absolute radiometric response and
does not state a specific downstream application of its own.
- wavelength-calibration/ — calibrates the pixel-to-wavelength axis of the spectrometer from Hg and Ne emission lamp lines.
- fel-lamp-calibration/ — calibrates the absolute spectral-irradiance response of the same spectrometer against a NIST-traceable FEL standard lamp.
The two pipelines solve unrelated calibration problems (wavelength axis
vs. radiometric response) and are kept in one repository because they
calibrate the same physical instrument — in the wavelength-calibration
script's own words, the two are otherwise "unrelated ... beyond
sharing a project." They also share a leave-one-out cross-validation
discipline — used for model selection in one case and for robust
outlier rejection in the other. Each subfolder is self-contained, with
its own README, inputs, outputs, and a legacy/ folder documenting the
earlier iterations that led to the current script.

José Helder F. Severo (University of São Paulo), the author's postdoctoral supervisor, proposed the calibration work documented in this repository and provided the equipment used throughout — the Ocean Optics USB4000 spectrometer, the Hg and Ne calibration lamps, and the Eppley FEL standard lamp with its calibration certificate — and supervised the initial operation of the lamps' high-voltage power supplies. He is listed as a co-author in CITATION.cff for these contributions, not for authorship of the code.
Leonardo G. Sgubin (University of São Paulo) introduced the SpectraSuite software and collaborated on the initial data collections. He is listed as a co-author in CITATION.cff for these contributions, not for authorship of the code.
