Theoretical prediction of variance σ2 for systems with different degree scaling exponents.
The system has size 
and power-law degree distribution 
with different values of the degree exponent: (a–d) 
, 2.5, 2.7, 3.0, respectively. In each case, the value of the pinning pattern indicator 
ranges from 0.6 to 1.0.
