| * //**Main page:**// [[http://www.planetary.brown.edu/relab/]] or at PDS [[https://pds-geosciences.wustl.edu/missions/mro/spectral_library.htm]] | * //**Main page:**// [[https://www.fabrizionestola.com/rch]] |
| * //**Short description:**// database from KECK/NASA (US) focused on the reflectance spectra of minerals and some other natural and man-made materials over the near UV to Near-IR or Mid/Far-IR (0.2-150µm) | * //**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:**// [[https://pds-speclib.rsl.wustl.edu/search.aspx|RELAB database]] | * //**Access to data:**// Only through plots from the software. Data cannot currently be downloaded. |
| * //**Sample types:**// Minerals (4650), Rocks (3100), Meteorites (2600), Lunar samples (1160), organics (380), synthetic materials (3000) and various mixtures (3000) | * //**Sample types:**// Minerals (1087), mineral inclusions in diamond (50), and synthetic materials (56) |
| * //**Spectra types:**// Reflectance spectra over the Visible to Near-IR (0.3-2.5µm) or Mid/Far-IR (-150µm) | * //**Spectra types:**// Raman spectra over the Mid/Far-IR (mainly 50-2000 cm-1) |
| * //**Search tools:**// Interface with Keyword, Chemical composition, Sample origin, type and size, Material type, sub-type and state, Mineral or rock type, Measurement type, Spectral range, Observation geometry | * //**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:**// ASCII (.tab) | * //**Data format:**// currently no download of individual spectrum (v1.0): screen copy |
| * //**Preview format:**// dynamic | * //**Preview format:**// dynamic |
| * //**Metadata:**// Sample ID and name, Particle Size Range, Collection location, Provider, Material origin, state and type, Mineral typa and subtype, Spectral range, Measurement geometry. | * //**Metadata:**// Sample ID and name, locality (origin), source (provider), RIR (?), chemical composition, laser wavelength, sample orientation, reference |
| * //**Metadata format:**// XML (.xml) | * //**Metadata format:**// currently not downloadable (v1.0): screen copy |
| * //**Download:**// via cart and HTTP (zip) | * //**Download:**// unavailable |
| * //**Notes:**// | * //**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. |
