<p class="MsoNormal"><span style="color:black">We have tried to address the subjectivity inherent in orientation estimates by using a well-documented and largely automated method that yields realistic uncertainties and results that can be easily reproduced.
We’d welcome feedback on this approach and on the AACSE measurements themselves.<o:p></o:p></span></p>
