[evlatests] Sensitivities

[Rick Perley]

    The spectral line data from last night were used to check delays, 
bandpasses, and sensitivites. 

    Delays and bandpasses look normal. 

    Sensitivites:

    L-Band:  Generally as expected (somewhat lower than VLA).  23B (the 
only working IF) is very poor in SNR. 

    C-Band:  All are outstanding, except antenna 17 (which is still 
better than any VLA antenna, but much worse than other EVLA antennas).  
Tsys for 17 is reported as 70K. 

    X-Band:    All are excellent, except antenna 17, for which the 
reported Tsys is 80K. 

    K-Band:  Antennas 16, 17, 18, and 26 are excellent (better than 
nearly all VLA antennas) in all IFs.  23B (the only working IF for that 
antenna) was also excellent. 
                   Antennas 14 and 24 are very poor.  Tsys for the 
latter is reported as over 100K. 
                   The others are about average. 

    No observations were made at Qband.
