Outlier This icon means
that the value is more than 2 standard deviations away from the
property mean.
Calculated This icon marks a calculated value or equation: a prediction, not a measurement.
Compiled This icon marks a compiled value or equation: taken from a data compilation such as ChemSep, not from an original measurement report.
These property values are available through the Cheméo API. A free account gives you an access key.
