Fig. 46

Marginalized posterior distributions for the fractional contribution, f10, of the defect contribution to the temperature power spectrum at = 10 (see the text for the precise definition). Here we show the constraints for the Nambu-Goto cosmic strings (NG, solid black), field-theory simulations of Abelian-Higgs cosmic strings (AH, solid red), semi-local strings (SL, dotted blue), and global textures (TX, dashed green). The upper panel shows the 1D posterior for the Planck+lowP data, while constraints shown in the lower panel additionally use the TE and EE data.
