Data for each column of the data file are flagged with a single
alpha-numeric code such that the first digit holds the
first data column flag, the second digit holds the second data column
flag, etc. Possible flags are 0-9, A-Z, a-z; however flag definitions are
currently as follows:
0 - No known bad data;
1 - Known bad data: instrument malfunction/failure, loss of memory,
loss of power, bio-fouling, electronic malfunction;
2 - Suspicious data (looks bad, but no known cause);
9 - Missing data (data column has a missing value code as defined in the metadata)
