Abstract

This paper discusses measurements of eight selected diffuse interstellar bands (DIBs): lambda lambda 5793, 5809, 5819, 5828, 6196, 6397, 6614 and 6660 performed in high resolution, high S/N spectra of 41 reddened stars. Central depths, considered less error-prone than equivalent widths, are measured and mutual correlations between the selected DIBs are analyzed. Tight correlations between the DIBs: 5809, 6196, 6614 and 6660 may suggest their common origin despite their widths differing by a factor of up to 2. The performed simulations prove that this fact does not preclude a common, molecularcarrier of such features.
