Table 7-3. Data group 2 has environmental information without any flux results.
Group 3: Performance information and diagnostics
Group 3 includes diagnostic and performance information for the LI-710. The Data
QC parameter may be of interest. It indicates how many points were discarded in
the processing of the raw data. A high percentage of excluded data indicates that the
measurement has poor quality.
