    Listed here are the particular issues found from the 'flux 
densities' run that were noted at X-band/

    ea05A:  PDif highly variable between scans.  Looks like some sort of 
bad switch effect. 

    ea12B and D:  System temperature very high -- 140K.   Tsys high also 
in IFs A and C, but not as bad:  43K. 


    That's it!  Everything else looks very good indeed.
