We took a Bull's eys scan on May 4th 2011 [1]. Both BPMA and BPMB had been scaned at different points along BeO target plane.
The Bull's eys scan run info is:
CODA Harp BPMA.x BPMA.y BPMB.x BPMB.y Run Run 4139 2553,2554 0.681368 0.31339 -1.49916 1.99701 4140 2555 2.01697 2.00781 -1.50599 1.99984 4141 2556 -2.00735 2.00558 -1.50115 1.99554 4142 2557 -2.0888 -1.9272 -1.49965 1.99597 4143 2558 2.00664 -2.00174 -1.49346 2.0128 4144 2559 0.652493 0.359911 -1.49973 3.99259 4145 2559 0.654841 0.359902 -1.49445 4.00451 4146 2560 1.08372 0.361684 0.502191 4.00373 4147 2561 1.08398 -0.454598 0.49695 0.495212 4148 2562 0.226162 -0.45363 -3.50121 0.496028 4149 2563 0.215757 0.364407 -3.49512 4.00087
Where BPM info are gethered from EPICS since the reading from Harp data is not reliable due to the true that the Harp has not been surveyed for the long time and there are some unknown offsets.
Here is the calibration resut of BPM:
[BPMA] -7.345 0.01887 1.1 1.1 0x267 0x21f 0x189 0x196 0.668999 -0.684665 0.672353 0.683605 0.000147627 -0.00063362 [BPMB] -2.214 0.01887 1.1 1.1 524 490 493 545 0.659737 -0.836241 0.646295 0.839493 0.00493647 -0.00602042
