R1a1 frequencies in Southeastern Europe

I have compiled frequency data for haplogroup R1a1 in southeastern Europe and Ukraine, the putative source of the R1a1 expansion in Europe. Let me know if there are additional studies to be included here. Also, R1a frequencies were used from some older studies (e.g., Rosser), but this shouldn't be a problem since R1a and R1a1 are almost always equivalent. The sources are also listed, and in most cases you should be able to track down the relevant papers on PubMed using the lead researcher's last name. Post any corrections/additional info in the comments.
