Table 1. Fitted von Mises distribution parameters.
Κ is the inverse of the variance (1/degrees2) and μ is the mean of each set of cell angles (degrees). “US” and “S” refer to unstrained and strained films, respectively, “perp” refers to microgrooves oriented perpendicular to applied strain and “para” refers to microgrooves oriented parallel to the applied strain. For all data, the angle is measured from strain axis. Values are average fitted parameters over all films used for the given combination of orientation and groove width (n = 3 or 4).
