[PICO\]BASEBANDS [Code1 Code2 Code3 Code4] [/SINGLEPOLAR]
After a EMIR tuning (one or more bands), defines what are the spectral
ranges that are sent to the Backends through the 8 available IF cables.
On the plot, the selected basebands are identified with their name (see
below). Baseband which will not be brought towards the backends are
filled in light grey. If the current plot corresponds to the result of a
tuning, the plot is not redrawn. Otherwise the current plot is redrawn.
Without arguments, an automatic selection is performed. When more than
one receiver band are tuned, the default maximises the coverage of the
FTS units and selects dual polarization when possible (losing a sideband
in each receiver band).
With the option /SINGLEPOLAR, the coverage of the FTS is still maximum,
but only one polarization is selected in order to process the two side-
bands in both receiver bands.
When codes are given, then the selection is up to the user. This might
be needed to send OUTER basebands towards WILMA and VESPA backends. 4
codes as inputs are required to set the content of the IF cables 1 to 4.
The content of IF cables 5 to 8 is not flexible and is the outer base-
band of the Receiver/Sideband/Polarization combination chosen for cables
1 to 4).
The format of the Code is: BBPSB
BandName (2 characters) : BB = E0, E1, E2 or E3 for EMIR
bands E090, E150, E230 or E350
Polar (1 character) : P = H or V
Sideband (1 character) : S = U or L
Baseband (1 character) : B = I or O
