./plotter bdrop.pro
| bdrop |
procedure bdrop, nchan |
This procedure is used to specify how many channels at the beginning of the spectrum should be ignored, when plotting. You then avoid the bad autoscaling that can result when the edge of the spectrum contains bad values. Note that the values are applied in channel space, so depending on whether the plot is shown in channels, frequency, or velocity, a bdrop value may affect the left or right side of the plotted spectrum.
show ; show some spectrum with bad channels bdrop,10 ; the spectrum is replotted with better scaling bdrop,0 ; unset the bdrop value
