[Dsg-rich] Residuals for RICH mirror assembly sphere fit

[Tyler Lemon]

Hello, 

It seems the histograms were not attached in my last email. They are attached in this reply. The histogram in blue is for the mirror assembly surface; histogram in green is the back assembly surface. 

Best regards, 
Tyler

Hello, 

We calculated the residual for each CMM data point compared to the ideal mirror radius of curvature (2700 [mm]). 

Below is the mean residual. This was calculated using the raw residual data for the assembly mirror surface and the assembly back surface. Also attached below are histograms of the raw data for each surface. 

Using this raw data, we will fit a Gaussian to the histograms. 

Mirror Surface: 
Mean residual = 1.288 [mm] ± 0.279 [mm] 

Back Surface: 
Mean residual = 0.501 [mm] ± 0.268 [mm] 

Best regards, 
Tyler
