Short description: The RCH software allows users to process their spectra using a variety of methods including, baseline corrections, smoothing, normalization, Raman shift calibration, add/subtract/replace functions, derivative determination, fitting and spectrum ID via comparison with the independent, on-board Raman database (RCHDB).

Access to data: Only through plots from the software. Data cannot currently be downloaded.

Sample types: Minerals (1087), mineral inclusions in diamond (50), and synthetic materials (56)

Spectra types: Raman spectra over the Mid/Far-IR (mainly 50-2000 cm-1)

Search tools: Interface through the software. Allow to seach by best fit of part or all your spectrum, or by peak position (+ intensity and width) or through the alphabetic list of minerals.

Data format: currently no download of individual spectrum (v1.0): screen copy

Preview format: dynamic

Metadata: Sample ID and name, locality (origin), source (provider), RIR (?), chemical composition, laser wavelength, sample orientation, reference

Metadata format: currently not downloadable (v1.0): screen copy

Download: unavailable

Notes: Currently (v1.0 / 2025) with a few bugs in the software, and no way to download a spectrum of the database but planned to evolve very soon.
