Quality flag

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 (e.g. missing value)
 * > = 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.
