But from which papers?
Behar 2013, "No Evidence from Genome-Wide Data of a Khazar Origin for the Ashkenazi Jews", has 11 Poles from Estonia and 7 Poles from Poland. I checked Supplemental File 1 to see their origins.
Geographical coordinates for these 7 Poles are listed there as 52.9743978146, 19.6763955101 (which is in Mazovia), but according to Davidski, they are actually from Warsaw (also in Mazovia).
These 7 Poles from Behar 2013 are on GEDmatch Genesis. I checked their GEDmatch results and compared them with my regional non-scientific samples. And they plot with other Mazovians.
Harvard also has Poles from Poznan (15) and Lublin (8) in their dataset, but these genomes are not publicly available:
