Once completed (approx 1 minute) the plots are updated with the calibration response. Plotted on the x axis is the device motor position (horizontal - left plot and vertical - right plot) and on the y axis is plotted the normalized horizontal or vertical diode pair response. For a good setup the plot should be a straight line through the 3 data points. Once completed (approx 1 minute) the plots are updated with the calibration response.

If you are happy with the calibration, press the "Push results/elog" button where the new calibration data is sent to the required data processing pipelines. After an automated restart (~30 seconds) both PV and BS position and intensity data will be calculated with the new calibration. An elog entry is made detailing the calibration data.

## Error
**Soft limits**
Error message: `ERROR: Motor position outside soft limits`
Problem is a soft limit on either the device Motor X or Y is blocking the scan motion
1. Select all from drop down menu for motor X and motor Y of PBPS GUI (shown below)
2. Change motor soft limits to 1 and -1 for both motors
3. Retry calibration
