I suppose  didn't look at the map correctly. if you print map of media Atropatne and north west Iran it is obvious that its is bigger than east Azerbaijan, west Azerbaijan, Ardabil and Zanjan provinces. in west part it includes definitely entire West Azerbaijan province and north part of Kurdistan province including its center Sanandaj.
We should not be biased to any ethnic in wikipedia. any statement should be based on history, geography and current demography.
