Instrumental profile of the HSFA-type spectrograph in the near infrared.
Abstract
A method of determining the instrumental profile of the horizontal solar spectrograph (HSFA) using an infrared sensitized photographic emulsion is described. Instrumental profiles, which include the effects of the non-zero slit width, diffraction and photographic emulsion along with possible distortions of the theoretical instrumental profile were determined by numerical convolution and deconvolution.
