Reflectance is shown on a fixed 0–1 axis (0.2 = 20%). Values outside this display range remain in the downloadable data. Values are read from the library without smoothing, clipping or extrapolation.

The acquisition instrument identifies the original measurement. Other sensor representations, including satellite bands, are provided as stored in the workbook; they are not additional satellite observations of this sample.

Missing values and gaps in densely sampled spectra are left open. Multispectral sensors are shown as discrete band points. The 400–700 nm rainbow follows LjGet_RGB_wavelengths, using CIE 1931 and the ICC white point.
