I did one iteration of dp calibration with LHRS straight through optics
data 3177, 3183, 3185, 3187, 3192 (after one iteration of angular
calibrations of theta and phi).


From the figure, the resolution is less than 2E-4. 

I made a cut on central hole to do the calibration, will see how the
resolution change with entire events.
