With the 25 distribution parameter labelled as *width*, the value *width=0* is 26 is assumed to be completely oriented and no polydispersity distribution 27 is generated. However a value of $a=0$ should be completely unoriented. 28 Any small value (e.g., 0.01 or lower) should suffice. 23 29 24 30 The order parameter $P_2$ is defined as … … 57 63 58 64 [1] Hardouin, et al., 1995.
