Simulation of the effect of the S/N on the observed azimuthal variations. Each column corresponds to one set of simulation using different f_clip values. A higher f_clip corresponds to applying a higher Hα threshold on spaxels entering the analysis, in other words, poorer S/N data. The starting point of the analysis (left column) is at 1000 pc resolution, the same as the lower bottom panel of Fig. 12. The different rows present the abundance residual distributions (top), the abundance maps (middle), and the abundance residual maps (bottom). The observed azimuthal variations decreases with increasing f_clip (decreasing S/N),
