NOTES
Tests applied are determined by data/processing type, as summarized
in the table below. Note that some of these tests are non-realtime and 
done with daily comparison of plots of similar datasets. 

SENSORS
8; 8m; Directional Array of 15 Pressure Sensors; BASE
D; DW; Datawell Directional Buoy; BASE
N; NB; Non-directional Buoy; BASE
P; PR; Single Point Pressure Sensor; BASE
B; BW; Baylor Wave Staff; BASE
A; AP; Acoustic Current Profiler (only Spectral QC); BASE

TESTS
SECTION: TIME SERIES VALUES
ALL;        GAP TEST; edit or discard time series with missing values.
D;          DW STATUS/TRANSMISSION BYTE; discard imperfectly received data.
8,D,N,P,B;  SPIKE EDIT; replace spikes with average of next point and previous.
8,D,N,P,B;  JUMP EDIT (ACCELERATION); replace jumps with average of next point and previous.
8,D,N,P,B;  RANGE TEST (TS); check time series for unreasonable values
8,D,N,P;    VALID MEAN TEST; check if the mean is in valid range
8,D,N,P,B;  UNCORRECTED ENERGY COMPARISON; compare time series variance.
8;          DEPTH COMPARISON; compare time series means.
8,D,A;      SERIES COMPARISON; check correlation of time series.
SECTION: SPECTRAL VALUES
8,D,N,P,B,A;INCIDENT WAVE TEST; check that directions are incident to shore.
D;          DW STATUS/TRANSMISSION BYTE; discard imperfectly transmitted data.
;           BAND DIRECTION MAX/MIN; check Dmean for each band.
8,D,A;      CHECK FACTORS; issue warning for bad check factors.
8,D,A;      SPECTRAL COMPARISON; good flag matching spectra (multiple transmissions, multiple gages).
8,D,;       INTERCHANNEL COHERENCE; averaged over half power bandwidth.
ALL;        SIGNAL TO NOISE TEST; flag low signal to noise records.
SECTION: PARAMETER VALUES
8,D,N,P,B;  SPIKE TEST; check for abrupt changes in values between records.
ALL;        RANGE TEST (PM); apply max/min tests to all parameters.
;           CONSECUTIVE VALUE TEST; check for excessively constant values.
8,D;        Dp SPREAD TEST; check if Dp values are too spread out.
;           Dp RANDOM TEST; check if Dp values are too variable and random.
ALL;        VISUAL INSPECTION; review daily and monthly Hs, Tp, Dp plots.
