Abstract

Two methods for calibration and wavelength calculation for echelle spectrograms are discussed. The rough method employing ruler measurements on photographic enlargements has an accuracy of about 1 in 105. The accurate method using comparator measurements of Th standard lines and a computer routine has given an accuracy of 2 in 107 and promises greater precision for spectrograms obtained with modern echelle gratings.
