Attached are the initial angular and dp calibration results on RHRS with straight through data (Gep setting). For this iteration, I used dp=0% sieve data to do angular calib, and cut on central hole only to do dp calib. Looking at dp plot, they represent -3.5%, -1%, 0%, 2%, 3.5% respectively. \Delta in 2nd and 3rd pads are worse than others. I am going to include all dp scan sieve data for angular calib, and data from all holes to do dp calib. In this way, data will cover much more phase space, thus the fitting polynomial will describe data more accurately. Beam position calib is desirable too.
