Fiber Attenuation Length Test -Update- Jaewon Park University of Rochester Jupiter/MINERvA Meeting, Dec 7, 2005
Reflectivity was about 0.8
Raw data plot with double exp fit
Check each component of double exponential curve
Reverse check Assuming reflectivity is 0.8
175ppm_ ppm_ ppm_ ppm_002
Fit unmirrored fiber and get fit parameters and then substitute them to mirrored attenuation formula and fit reflectivity
