The data shown are for V0=10.8 Erec (squares) and V0=11.44 Erec (circles). The red dashed (dash-dotted) line is obtained by fitting the last four data points with equation (3) using the average filling 
as a fitting parameter. We obtain respectively 
and 
. The data for V0=10.8 Erec are shifted along the vertical axis by 0.1. The error bars represent the statistical variance of typically 4–5 independent measurements.
