The baffle by HAM2  can, at 5 degrees, specularly reflect some scattered light back to beam spots and has been shown to produce scattering noise (https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=74772). Today we changed the angle of the baffle to 10 degrees using new hardware designed at CIT. The new hardware and the procedure worked well. The figure shows photos of the work.
