      tune spectral to tristimulus and internal spectral representation · 9f5baf97
      Øyvind "pippin" Kolås authored
      Now using 5nm band size, 360-780 range and CIE 1931 standard observer
      and D50 illuminant for the conversion. To specify what spectral data
      means in relation to colorimetry we need to specify the wavelength
      range, observer and illuminant expected.
      
      When experimenting with HLC-Colour-Atlas-XL_SpectralData_v1-2.cxf the
      inaccuracies of the spectal data resampler in coloritto have become
      apparent, for now - using 5nm provides the best results for all input
      data wavelengths - resampling with bandpass filtering and work to avoid
      shifting the data is needed.
      
      The 360-780 range is the range recommended by E308 and probably other
      attempts at standardising spectral to tristimulus conversions.
