MultiplyByEnergy

If G is a spectra object then G.MultiplyByEnergy() Multiplies a spectrum G($\omega$) by its energy, i.e. Gnew($\omega$) = $\omega\times$G($\omega$). G.MultiplyByEnergy is similar to the function Spectra.MultiplyByEnergy with the difference that it does not make a copy of the spectra object.

Example

Take the spectrum defined in the file definitions.Quanty and multiply it with its energy.

Input

Example.Quanty
dofile("definitions.Quanty")
 
G.Print({{"file","Spectra.dat"}})
G.MultiplyByEnergy()
G.Print({{"file","Spectra.MultiplyByEnergy.dat"}})
 
 
gnuplotScript = gnuplotHead .. [[
set output "Spectra.MultiplyByEnergy.ps"
plot "Spectra.dat"  using 1:(-$3  ) title 'T1' with lines ls  1,\
     "Spectra.MultiplyByEnergy.dat"  using 1:(-$3) title 'T1 * Energy' with lines ls  2
]]
 
file = io.open("Spectra.MultiplyByEnergy.gnuplot", "w")
file:write(gnuplotScript)
file:close()
 
os.execute("gnuplot Spectra.MultiplyByEnergy.gnuplot")
os.execute("convert -density 1024 Spectra.MultiplyByEnergy.ps -resize 1024 Spectra.MultiplyByEnergy.png")
