Comments:

This includes data from 2008-001-FA that isn't indicated in the publication or the metadata. Dave Foster was able to figure this out. This review of this dataset (and the associated OFR) occurred several years before the OFR actually came out - so it appears some changes took place that weren't covered in the review.
