What is the flag variable column that is added to the data file by SBE Data Processing's Data Conversion or ASCII In module?

The flag variable column is added by Data Conversion (if you process data using Sea-Bird software) or ASCII In (if you are importing data that was generated using other software). The Loop Edit module sets the flag variable to bad for scans that show a pressure slowdown or reversal. The flag variable is then used by the rest of the SBE Data Processing modules as an indication of a bad scan, allowing you to exclude scans that are marked bad from processing performed in a module, if desired.

Initially all scans are marked good (flag value of 0) in Data Conversion or ASCII In. A flag of -9.99e-29 indicates the scan has been marked bad by Loop Edit.

Note: All occurrences of the bad value (-9.99e-29) can be replaced with a different value in ASCII Out. This may be useful for plotting purposes, as -9.99e-29 looks like 0 in a data plot.
