For these I use vtnspec to produce the spectrum data,
awk assembles it into a data file and gnuplot does
the rest with its pm3d map mode.

I attach two scripts, one prepares the spectra and
the other does the plot.

I just alter the T1 and T2 in both scripts to set
the time range, and sometimes I remember to alter
the set title command to match.
