The PLOT command is used to change the plot options and update the plot
accordingly. Except for some restrictions on /LIMITS, the options are
valid for all observatories.
Three types of plots can be produced for the Plateau de Bure:
o LINE mode = plot of the LSB and USB (as produced by the LINE command).
Note that the new generation receivers at PdBI are single-side band: the
image sideband appears in light grey. Widex and Narrow-band units are
o NARROW mode = SSB plot of the two selected entries of the narrow-band
correlator. This plot is aimed at zooming on the two 1 GHz inputs of the
correlator, as selected by the NARROW_INPUT command. The position and
width of the 8 spectral units are drawn.
o WIDEX mode = plot of the WIDEX frequency coverage.
Two types of plots can be produced for ALMA :
o FREQUENCY mode = plot of the LSB and USB ouptut of the receiver band
(as produced by the FREQUENCY command).
o BASEBAND mode = plot of the baseband #i. The position and width of the
spectral windows defined with SPWINDOW are also drawn.
After each of the LINE, NARROW_BAND, SPECTRAL or WIDEX commands, the
plot is updated.
