IGOSS qualityflag (5 digits):

First digit:       Pressure quality

Second digit:   Temperature quality

Third digit:       Salinity quality

Fourth digit:    Conductivity quality

Fifth digit:        Depth quality

0 - No quality control          No quality control has been performed.

1 - Correct                           Appears to be correct.

2 - Inconsistent                   Appears to be inconsistent with other elements.

3 - Doubtful                         Appears to be doubtful.

4 - Erroneous                      Appears to be erroneous. The flag indicates a value outside the permitted range.

5 - Corrected                       The value has been corrected. The flag inicates a change has been made by the
                                              operator. Only obvious errors are corrected. The previous value are not saved.

8 - Inter-/extrapolated      Reserved. Local definition: The value is interpolated/extrapolated by observer.
                                             Methods unspecified.

9 - Missing                         The value of the element is missing.
