UV spectrograms of the sun and of Alpha CMi are analyzed to investigate the effects of finite spectral resolution in the interpretation of stellar spectra veiled by lines. The recorded completeness of intrinsic spectral detail is examined by means of the ruggedness parameter of Ivanov and Salman-Zade (1976). Solar spectrograms of approximately 0.03 A resolution are a good representation of the true spectral distribution. The power of the Minnaert-Houtgast method for tracing line wings and establishing the local 'continuum' background in spectra crowded with lines is demonstrated.
