./plotter edrop.pro
edrop |
procedure edrop, nchan |
This procedure is used to specify how many channels at the end 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, an edrop value may affect the left or right side of the plotted spectrum
show ; show some spectrum with bad channels bdrop,10 ; edrop,10 ; the spectrum is replotted with better scaling edrop,0 ; unset the edrop value. bdrop is still in effect.
