Comparison of the anisotropy from exp with all models presented in paper has been done in addition.

Also please have a look into older HADES pion paper from CC. https://arxiv.org/pdf/0902.4377.pdf

You can see, that already in those old data similar trend of A2 as a function of p_cm was observed.

Plots below shows few spectra from models.

At the end what i would propouse for paper is as follows :

exchange Fig. 14 with following one

Centrality selection 0-10 % , left-handside : negative pions, right-handside : positive pions

on Fig. 13 instead of angular distribution from UrQMD show the fits, which are used to extract A2

exchange Fig. 15 with following

Below several additional plots can be found.

negative π

In the following plot all lines has been scaled at mid-rapidity in order to see comparison of the shape.

anisotropy as a function of center of mass for 4 centrality classes and 5 models in comparison to models.

positive π

Additional plots for negative π from EXP

Even more additional plots for negative π

Even more additi

onal plots for positive π
