Quality flag – PANGAEA Wiki

Each single numeric value in an import file can be quality flagged with symbols as listed below.
Insert the symbol at the beginning of a value without a blank in between.
Values without any symbol are qualified as being valid.

Quality flags with Symbol (examples in brackets):

• no symbol = valid (default)
• ? = questionable (?0.345)
• / = not valid (/23.56)
• * = unknown (*0.999)
• # = individual definition (#999)
• > = larger than (>123.7)
• < = less than (<123.7)

The new data warehouse interface additionally uses the following (new) quality flags to mark values generated by pre-processing (e.g. averaging):

• ø = averaged value (ø1.123)
• ± = standard deviation of averaged value (ø1.123±0.123)

In exported files, converted with Pan2Applic, the quality flags will be converted to those used by other applications.
