Cumulative System performance

     The cumulative system performance is plotted for each receiver. The plots are limited to 2000 measurements.  When something occurs that may change the gain of the system (moving a horn, shimming the elevation rails) then a new epoch will be started.  The old data is moved to the old system performance data page (the old data link points to this).

    The data is first plotted with all pixels together. Color is used to code the pixel number. After the combined plot there are 7 more plots showing each pixel by itself. For these plots  color is used to distinguish the source used. The data is 100 Mhz centered at 1420 Mhz. Old data
