Let A be the set of samples s in the analysis domain being considered. Then:

where
A= the set of samples in the analysis domain. Ns= The number of samples in the analysis domain subject to analysis = Samples. = 0 if sample s is not in the analysis domain 1 otherwise, inluding below threshold data
Note: This forms the denominator in the Sv_mean calculation for single beam data.
Let A be the set of samples s in the analysis domain being considered. Then:

where
A= the set of samples in the analysis domain. Nb= The number of bad data samples in the analysis domain = Bad_data_samples. bs= 1 if sample s is bad data 0 otherwise
Let A be the set of samples s in the analysis domain being considered. Then:

where
A= the set of samples in the analysis domain. Nn= The number of no data samples in the analysis domain = No_data_samples. hs= 1 if sample s is no data 0 otherwise
The total number of samples in an analysis domain which are not above an exclude-above line or below an exclude-below line can be calculated as:
Samples + Bad_data_samples + No_data_samples
A count of the total number of samples excluded is not currently available.
