110071: Diametrically bimodal data was found for <value> of <value> cases. The Rayleigh test is not valid for those cases and as a result, their output has been corrected for better representation of the mean direction.

Description

When data is pointing in opposite directions, it is said to be diametrically bimodal. The average angle of this data would be at a right angle of the true mean angle and a poor representation of the data. An angle-doubling procedure is applied to the cases that were found to be diametrically bimodal to result in a more representative output of the mean orientation.

Solution

No further action is necessary. As stated in the message, the output was corrected for the affected cases for better representation of the mean direction.
