Objective-prism and objective-grating spectrograms were obtained in six star fields during the Gemini 11 mission. The grating spectra show absorption lines in the 2000 to 3000 angstrom wavelength region of Canopus and Sirius and provide ultraviolet-energy distribution data for approximately 50 stars. Many prism spectra show the Balmer discontinuity due to hydrogen and two absorption features probably due to ultraviolet iron multiplets.
在双子座 11 号任务期间，在六个星场获得了目标棱镜和目标光栅光谱。光栅光谱显示了船底座和天狼星在 2000 到 3000 埃波长区域的吸收线，并为大约 50 颗恒星提供了紫外能量分布数据。许多棱镜光谱显示了由于氢而产生的巴尔默不连续性，以及两个可能由于紫外铁多重线而产生的吸收特征。
