1  ABAZOV 2017 based on 9.7 fb${}^{-1}$ of data. The value is top quark polarization times spin analyzing power in the beam basis. Combination with the result of ABAZOV 2015K yields $0.081$ $\pm0.048$. This result together with the helicity polarization is shown in a 2-dimensional plot in Fig.4. These results are consistent with the SM prediction.

3  ABAZOV 2017 based on 9.7 fb${}^{-1}$ of data. The value is top quark polarization times spin analyzing power in the transverse basis. The result is consistent with the SM prediction.
4  ABAZOV 2015K based on 9.7 fb${}^{-1}$ of data. The value is top quark polarization times spin analyzing power in the beam basis. The result is consistent with the SM prediction of $-0.0019$ $\pm0.0005$.
