Six absorption lines detected toward PKS 1830–211, displayed in five panels with a local standard of rest (LSR) velocity scale relative to z = 0.88582 (V_LSR = V_HEL + 12.4 km s^-1; ordinate: absorption depth in units of percent of the observed continuum flux density, T_C, accounting for the entire source). The spectra were taken between August and December 2001. The velocity scale of the fourth panel from the top is based on the E-transition of methanol (CH₃OH). The scale for the A-transition is offset by 27.5 km s^-1. The cyclic-C₃H₂ line of the central panel belongs to the para species (see Table 2). Channel spacings are 1.4, 1.4, 1.7, 0.9 and 3.0 km s^-1from top to bottom.
