Although jet rotation has been observed in a few objects, no rotation of molecular outflows has been unambiguously reported so far. We report new millimeter-interferometric observations of the edge-on T-Tauri-star - disk system in the isolated Bok globule CB-26. The aim of these observations was to study the disk-outflow relation in this 1Myr old low-mass young stellar object. Description: The IRAM PdBI array was used to observe ^12^CO(2-1) at 1.3mm in two configurations, resulting in spectral line maps with 1.5" resolution. We use an empirical parameterized steady-state outflow model combined with 2-D line radiative transfer calculations and chi^2^-minimization in parameter space to derive a best-fit model and constrain parameters of the outflow.
