摘要: We present an atlas of 271 diffuse interstellar bands (DIBs) between 4460 and 8800 A based on echelle spectra (R = 45,000), which more than 100 are new DIBs discovered in this survey. The is restricted mostly to narrow features, we describe the tests for origin. rest wavelength each DIB was determined a high-quality composite spectrum star HD 23180 using Na i (D1 D2) lines establish radial velocity single intervening cloud. wavelengths quoted 0.01 probably accurate ~0.1 A. Other, weak found heavily reddened stars included with lower precision.
