DC was quite misaligned after changing sample..
after realignment
Pt = 26.1mW ; Pin = 30.0mW
rotated HWP to 28deg : Pt = 4.82W
long z scan : Mon, Apr 1, 2024 9-05-41 AM.txt
z edges at 29.5 and 58.5 mm : z_center = 44 mm
Pt = 4.84W
map at z_center : Mon, Apr 1, 2024 10-26-52 AM.txt
after visit break Pt~4.9W
z = 34 mm : Mon, Apr 1, 2024 4-44-36 PM.txt
z = 54mm, Pt = 4.85W : Mon, Apr 1, 2024 11-58-05 PM.txt
this sample is t50#2
