Left shows a scatter plot of reference diameters against the remotely sensed and automatically extracted diameter eter measurements. This does contain the measurements which have been not successfully matched amongst reference and measurements. This does notnot include things like the measurements which were not successfully matchedbetween reference and automatic datasets. Right supplies a histogram to visualise the distribution on the BSJ-01-175 MedChemExpress measurement errors. automatic datasets. Appropriate gives a histogram to visualise the distribution with the measurement errors.3.four. Tree and Measurement Detection Completeness three.four.
