An atlas of solar spectra between 1175 and 1950 angstroms recorded on Skylab with the NRL's Apollo telescope mount experiment

摘要

Spectra of selected solar regions were recorded by the Naval Research Laboratory slit spectrograph on the Apollo Telescope Mount aboard Skylab. This atlas of those spectra is intended as a guide to the formulation of experiments and analysis of data obtained by extreme ultraviolet spectrographs and may be valuable to investigators analyzing International Ultraviolet Explorer spectra and data from Solar Maximum Mission and High Resolution Telescope Spectrograph. The slit spectrograph was used to cover the range 1175 A to 1950 A with a spectral resolution of 0.06 A and a spatial resolution at Sun center of 2 deg by 30 deg. Microdensitometer tracings of spectra from (1) a quiet region, (2) an active region, (3) a coronal hole, and (4) a flare are included and were computer processed to include the characteristic curve of the film. Line identifications for prominent features are included as well as a reference scale permitting the user to obtain absolute intensities.
