Profiles of the variable lines observed in the RZ Psc spectra during the MRES run. The velocities in km s^-1 of the circumstellar absorptions are labeled. The reference photospheric profiles of the Na i λ5889 and K i λ7699 are plotted with a dashed line (see the text for details). In the case of the Hα line, the spectrum of the σ Dra convolved with the corresponding instrumental and rotational kernels was used as reference. For the Ca ii λ8542, the dashed line indicates the synthetic profile.
