TIME SERIES (Raw Calibrated Data) |
Data Gaps |
Consecutive N missing data. Maximum number of missing data. |
1 |
Soft |
N is user defined. Include in % count. |
Spikes |
User defined Points >= M*std with P iterations |
2 |
Soft |
Interpolate/extrapolate up to N points. N is user defined. M can be user
defined, recommended M=4. Include in % count. |
Range test |
Location, instrument defined. |
2 |
1. Soft
2. Hard |
Max/min user defined.
1. Interpolate/extrapolate up to n points. N is user defined.
Include in % count.
2. Instrument spec exceeded, reject.
|
Mean shift (segments) |
A mean shift "P" occurs in this time series. |
3 |
Hard |
Reject entire record. P is user defined. |
Acceleration test |
User defined (a>M*g) |
3 |
Soft |
Recommended M<=1/2. Interpolate/extrapolate up to N contiguous points. N is user defined.
Include in % count. |
Mean test, variance test |
User defined, location dependent |
4 |
1. Soft
2. Hard |
1. Flag unexpected values.
2. Reject unreasonable values. |
Percent points good |
Check for M% good data (based on above 6 criteria) |
5 |
Hard |
Recommended M>=90% |
