The effects of fringing magnetic fields on the electron spectral measurements and the accuracy of density scale-length measurements are evaluated. 2D EPOCH PIC code simulations are found to be in agreement with measurements of the electron energy spectra showing that laser filamentation in plasma preformed by a prepulse is important with longer plasma scale lengths (> 8 mu m).enArticle934info:eu-repo/semantics/openAccess2-s2.0-84963604220WOS:0003735858000062717641310.1103/PhysRevE.93.043201Q1Q1
