## 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.
