A possible sets of diffuse bands originating at the same carrier

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