| Abstract: | Some peculiarities of the use of a laser for the determination of the instrumental profile of the high-resolution spectrograph have been described. The results of the investigation of the instrumental profile of the Kiev-Golosejevo double-pass solar spectrograph are presented in graphs.The influence of the width of the slits of the double-pass spectrograph upon the main features of its instrumental profile is discussed briefly. |
