Installation of the new Ka-band receivers on EVLA antennas has
begun. See the relevant section for the
current status. Figures 1 and 2 show the effective Tsys
and the D-terms for a few selected antennas equipped with the new
receivers. Note that Ka-band specific models for amplitude
calibrators are not available yet, and models for K and Q band will
have to be used for the time being. More details can be found here.
