The p-local stable Adams conjecture: Erratum

This erratum remedies errors in the literature pertaining to the stable Adams conjecture. As part of the above corrections, we also identify and fix two errors in section 4 of our recent article on the subject. We thank E. Fridelander for flagging these oversights and for offering helpful suggestions. This erratum is self-contained and also includes an appendix proving a version of Friedlander's classification result for sectioned fibrations of Gamma-spaces, after making appropriate changes to the original statement as indicated in the appendix.
