It's SNP voting levels from 2012 elections - not a particularly appropriate measure in my opinion!
Edit: The reason why I don't think it's appropriate is that it is a simple "Yes" or "No" and a lot of people who may have traditionally voted Labour or Lib Dem might be voting "Yes" even though the national UK parties have all been pushing the "No" side of the campaign.

Agreed. That's way off base. SNP voters won't make up half of the YES vote.
Its unpredictable as it's all down to how the Labour and previous non-voters fall.
