As Rick mentioned I am reporting on the C and X band tests.   
Generally the system is working well.  I only have a few things to  
mention.

General notes: 1 is in the barn so was out for the entire run, all  
data were loaded with the correlation coefficients
C-band
A&C
      14, 25 out
      14's data is fine when loaded without the flags
      24 comes in late
      4 and 12 had dropouts
B&D
	25 out
         24 comes in late
	15D has "chirps" in the data - states of extremely high correlation  
coefficients
	4 and 12 had dropouts
Sensitivities
	EVLA sensitivities ~20% better than VLA
	11A has 25% too high correlation coefficients
	4AC,12AC has 30% too high correlation coefficients
Phase jumps
	NONE

X-band
A&C
	14 out but data are good when unflagged data loaded
	24 takes a while to come online
	25 comes online mid-way through observations
B&D
	24 takes a while to come online
	25 comes online mid-way through observations
	15D has "chirps" in the data - states of extremely high correlation  
coefficients
Sensitivities
	EVLA and VLA sensitivities approximately equivalent
	11ABCD has ~15% too high correlation coefficients
	14D has ~30% too high correlation coefficients
	15CD has ~10% too high correlation coefficients
	25ABCD has ~15% too high correlation coefficients
Phase jumps
	NONE
