 WR Errors
		 Base 		Current 	Difference
aida01 fault 	 0xf932 : 	 0xf933 : 	 1  
aida02 fault 	 0x62ec : 	 0x62ed : 	 1  
aida03 fault 	 0x8679 : 	 0x867a : 	 1

aida07 fault 	 0xdd2c : 	 0xdd2d : 	 1  
aida08 fault 	 0x1557 : 	 0x1558 : 	 1  
White Rabbit error counter test result: Passed 8, Failed 8

Understand the status reports as follows:-
Status bit 3 : White Rabbit decoder detected an error in the received data
Status bit 2 : Firmware registered WR error, no reload of Timestamp
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR

FPGA Errors
	
                Base Current Difference
aida05 fault 	 0x0 : 	 0x2 : 	 2  
FPGA Timestamp error counter test result: Passed 15, Failed 1
If any of these counts are reported as in error
The ASIC readout system has detected a timeslip.
That is the timestamp read from the time FIFO is not younger than the last

Statistics ok - attachment 1
 Temp ok - attachment 2
 Bias and leakage current ok - attachment 3

01:42 Comparing the CS of AIDA3 and 4
      Stats have been running for a while (Believe since 5am)
      Looking at the counter ratio - attachment 4
      We still have a deadtime of around 14% in FEE4 (Assuming FEE3 has no dead time)

01:56 Noticed /media/ThirdDrive was at 97% full
      Let DESPEC locals know I would like to use the next run stop to change the directory.
      They said they could do it now so they stopped their run.
      Changed the symbolic link to /media/1e2....
      Now writing to R4_

03:26 MBS DAQ Stopped as beam stopped
03:33 Beam back now and DAQ running again

04:44 System wide checks as before
      Statistics ok - attachment 5
      Temperatures ok - attachment - 7
      Bias and leakage currents ok - attachment 6

05:53 MBS stops run as beam drops
06:00 MBS started a new run as beam is back

07:37 System wide checks clock ok and FPGA as before
      WR additional difference on FEE5
