Abstract
We present the distribution of unpolarized quarks in a transversely polarized proton in three-dimensional momentum space. Our results are based on consistent extractions of the unpolarized and Sivers transverse momentum dependent parton distributions (TMDs).

Several changes compared to first version. Additional equations inserted, additional explanations, inclusion of normalization errors, inclusion of Z and W data points and corresponding plots. Results remained qualitatively similar to first version
