ASCIIdata Spectra in ASCII text files, including separate files with wavelength and bandpass (FWHM) values
ASCIIdata 
Files containing spectral data in ASCII text format: 
- measured spectra (ASCIIdata_splib07a.zip), including wavelength positions and bandpass (Full-Width at Half-Maximum; FWHM) values of channels in the spectrometers utilized  
- spectra interpolated to a higher number of  more finely-spaced channels …
