The TREx RGB unstable data was generated by TREx RGB systems using a previous version
of the instrument operational software, and is now deprecated. Data existing here is valid
for scientific use, but should be avoided for sake of consistency with the existing main
dataset, found in the stream0 directory one level up (H5 files). We also note that data
from the Yellowknife TREx RGB system does not exist in this unstable tree, but only exists
in the main stream0 tree.
