[Dsg-rich] RICH survey data

[Marco Mirazita]

Dear Kelly,
for the survey made in the Hall B after the installation, we need the 
coordinates of the surveyed points on the RICH in the CLAS12 reference 
frame.

Then there is the survey made in the clean room. From this, we need 
again the coordinates of the points on the RICH and of the points 
measured on the mirrors. The reference frame of these measurements was 
located on a point in front of the RICH as shown in the attached figure, 
but it would be very helpful if you could translate these coordinates in 
the CLAS12 reference frame.
I remember that your software extracted also the tilt angles of the 
mirrors, this would be another useful information to have.

Any data format would be fine for us, text, excel, or similar, but if 
possible we would like to have also the CAD files of the measurements.

Please let me know if you need any other information. I would be at JLab 
next week, so if necessary we could meet shortly.

Best regards,
Marco
