Definition of Quality Control Flags
  1. Depth Flags
  2. 0 - accepted value
    1 - error in recorded depth ( same or less than previous depth )
    2 - density inversion

  3. Observed Level Flags
  4. N - missing value
    0 - accepted value
    1 - range outlier ( outside of broad range check )
    2 - failed inversion check
