Saul -- I talked to Bahram about this. The earlier stuff was more
blurred and blended together since it was done at lower resolution.
Additionally, they *are* consistent, in that the PDFs overlap each
other.
Given the SN colors and magnitude, I'd be surprised if this were beyond
1.5-1.6, but that's not inconsistent with the current photo-z
information.
