About

The table contains the results from the calibration of operators for the estimation of the number of bees on frames. The persons who estimated colony size had to carry out a calibration immediately before the start of the estimation if the last calibration was more than a week ago. For the calibration, 20 photos of frames with a known number (578-1278) of bees were presented to the persons carrying out the estimation in order to determine measurement accuracy.
