SGP/EBBR/E8 - AEM Replacement
DataStreams:sgp15ebbrE8.b1, sgp5ebbrE8.b1, sgp30baebbrE8.c1, sgp30ebbrE8.b1
Description:
The AEM at E8 kept hanging in between home positions.

This DQR covers only the period during which the AEM was being
replaced.  

DQRs generally are not issued for AEMs that are not working
as qc flags indicate this clearly.
