This correction resolves a puzzling inconsistency: the excessive discrepancy of two orders of magnitude between results obtained with this analytic approximation and those of more detailed investigations (i.e. Ölmez, Mandic & Siemens ; Sanidas, Battye & Stappers ). In Sanidas et al. (), the authors presented an absolute upper limit on the string tension , using our limit on the amplitude of the stochastic gravitational wave background and taking into account the uncertainties involved in the cosmic string model parameters. The one order of magnitude difference between our revised constraint and their results is now well justified within the approximations of Damour & Vilenkin (). This is discussed in more detail by Sanidas et al. () and has recently been pointed out by Shlaer, Vilenkin & Loeb () as well.
