[@Polanew]. The relevant data sets and their polarisation values are listed in Table \[tab:pol\]. The polarisation values do not differ by more than 0.3% from the previously published values for any data set. The uncertainties on the integrated luminosities for all ZEUS HERAII samples were also re-evaluated using the final understanding of the luminosity system [@Zlumi3]. The uncertainty is 1.8% for almost all data taking periods. The uncorrelated part of this uncertainty is 1%.

Combined QCD and EW analysis
============================

The analysis presented here was performed at NLO in QCD. The DGLAP [@Gribov:1972ri; @Gribov:1972rt; @Lipatov:1974qm; @Dokshitzer:1977sg; @Altarelli:1977zs] formalism was used to describe the evolution of the PDFs with $Q^2$. The PDFs were parameterised at a starting scale of 1.9GeV$^2$. The analysis followed the method used to extract the set of PDFs called HERAPDF2.0 [@HERAPDF20] and its variants. The cross sections as predicted by perturbative QCD were fitted to the measured cross sections and PDF parameters were determined through $\chi^2$ minimisation. The fits were performed with the ZEUSFitter package[^2] and cross-checked with the HERAFitter [@HERAFitter] package.

To extract electroweak parameters, either the couplings of the $Z$ boson to the $u$- and $d$-type quarks or $\sin^2\theta_W$ and $M_W$ were additional free parameters
