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 points plotted per page are limited to the 2000 most recent points. This could make is so that the 1st multi frequency page could cover less time than the individual frequency pages. This constraint is not used for the az,za page or the hour of day page (these include all of the data).

I split the calibration plots into before maria and after maria for the active receivers.

327 receiver
430 dome receiver
430 ch (linefeed) receiver
610 receiver
800 receiver
lband narrow
lband wide
alfa
sband narrow
sband wide (2-3 Ghz)
sband high (3-4 Ghz)
cband (4-6 Ghz)
cbandHi (6-8 Ghz)
xband (8-10 Ghz)

alfa (lband feed array) (other alfa calibration info) (top)

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 1440 Mhz.
