It will be a little while until I collect more data due to travel and work so I decided to poke around on this data. Clearly, a long ways to go in collecting even enough NB data to get this where I want it. It is an exciting target and I look forward to giving it more time in both nb and rgb. In the meantime, as always, C&C's are much appreciated and thanks for looking!
