The data  set is organized as two set with 4 files:

TODDA1_Freq.dat-the frequencies
TODDA1_Imag.dat- the imaginary parts
TODDA1_Real.dat- the real parts 
TODDA1_Temp.dat- the temperatures
TODDA2_Freq.dat-the frequencies
TODDA2_Imag.dat- the imaginary parts
TODDA2_Real.dat- the real parts 
TODDA2_Temp.dat- the temperatures

TODDA.png gives the whole spectrum of data from both sets.
