Some other things

Any command may be aborted while it awaits input by typing Control-c.

Data may be `binned' (averaged) over n channels by typing

$>\!>$ bin n

and smoothed using

$>\!>$ hann

Several spectra may be plotted on the same frame to good effect by offsetting vertically with respect to one another using

$>\!>$ off-sp

and then using the over command.

One spectrum may be subtracted from another by using

$>\!>$ sub

or divided by another (channel-by-channel) by typing:

$>\!>$ f-q-s
