Abstract:

A catalog of links for advanced LIGO (aLIGO) era coating witness samples proveded by LMA for purposes of point absorber investigation and mitigation. Each sample is assigned a unique DCC number, then test data are linked to that branch.
Core Optics witness samples are found at E2000020
Master filecard for LMA samples found at E2000079
