Inflow	6.9259 $_{- 0.0005}^{+ 0.0001}$ $^{+0.0001}_{-0.0005}$	17.1 $_{- 0.1}^{+ 0.1}$ $^{+0.1}_{-0.1}$	7.7 $_{- 3.4}^{+ 3.6}$ $^{+3.6}_{-3.4}$	−0.41 $_{- 1.5}^{+ 0.1}$ $^{+0.1}_{-1.5}$

Notes. Errors are estimated from the spread in the posterior distribution. We find that the TS model with a free redshift yields the best results.
