Popis:	The well-known class-A quark-model relations of Bialas and Zalewski are parametrised in a particular form, where one can compare the data with the predictions separately for the meson non-flip and flip parts, defined in the transversity frame. A 3-parameter fit to the joint decay angular distribution is performed on the experimental data, and the results are compared with the quark-model predictions for various regions of the four-momentum transfer. The effect of an s -wave state under the ρ 0 is discussed.
