J. Uson reports that the spectral dynamic range he is achieving is much worse than in the last D configuration. He is trying to learn why. He sees all sorts of behaviors. Some are simple, slow functions of time. Some do not behave symmetrically about the meridian but otherwise vary smoothly.
Some antennas have an occasional jump.
Some are just unstable, antenna 3 in particular. There is probably a mine of information about various system problems in this data, if someone has the energy to work it. F. Owen adds that he has a curious behavior in current P band data. He sees occasional very strong signals, which are not obviously antenna based, and which occur in one polarization and not the other, as if there were a correlator problem, but it is not reasonable to have a correlator problem which occurs only at P band. Exploiting the phase vs. Tsys relation at K band.
