Fine-tuning the plot

The LINE, NARROW, and SPECTRAL commands produce plots that display the receiver and correlator setup of the instrument. Those plots can be further modified using the PLOT command, to e.g.:

• swap from a DSB-like plot (LSB and DSB reprensented) to a NARROW-like plot (two selected quarters are displayed), using PLOT DSB|NARROW;
• zoom on a particular IF region, typically if many lines are present, using PLOT /LIMITS min max;
• introduce a width for the molecular lines displayed (PLOT /WIDTH width);
• plot the location of possible spurious lines (PLOT /SPURIOUS).

See the on-line help for more details on the input parameters.
