Sumario:The optics commissioning strategy for low-$\beta ^{*}$ operation of the LHC underwent significant revision in 2017 [1]. The beam-based correction strategy transitioned from being concerned exclusively with linear optics errors, to a combined linear and nonlinear optics commissioning, with the traditional optics corrections at flat-orbit being both preceded and followed by corrections for the effect of nonlinear errors in the ATLAS and CMS insertions.
