I also measured the maximum counts vs. pickoff mirror position. It turns out that the positions where the counts reaches maximum doesn't agree with positions cophased with CHARA. I attached the file with the measurements, and will use the the maximum positions(marked with "*" in the file) for this run. I copied the positions that are cophased with CHARA and CHAMP, which are measured in June 2012.
cophased postions measured in 2012Jun.
