with the same value (repeating standard deviations or offset). Completeness Check whether the number of records and their sequence is correction (identification of gaps, check for repetition) X Range /threshold Check whether the data of each sensor lie within the measurement range of that sensor. X X Measurement continuity Compare the rate of change of a signal to expected/seasonally accepted values and between similar measurements that are collocated in close proximity X X Measurement Consistency comparison between statistics, such as the ratio of wave height to power X Near-by Comparison Comparison with similar/duplicate measurements that are collocated in close proximity X Spectral spikes Spikes in the spectral data X X Trends and inconsistencies Identify trends in data such as large drift in sensor output or inconstancies in sensor output for similar input X Data are transferred from the Carderock systems (Natural Point and the NI DAS) to the DA computers via an optical media, likely a re-writable DVD or Bluray. Each disc will be labeled with the data, the team name and the included runs. Separate discs will be used for each team.
