Notes.The adopted wavelength range, total number of angstroms and pixels, sampling, convolution FWHM, and resolution range are given. Also provided are the percentage of pixels for which the difference in flux between the Observed and the Synthetic is less than the limits of 5, 10 and 20%, for the comparison of the Sun and Arcturus Atlases to synthetic counterparts.
