____________________________________________________________________
The data format is defined as described below:

There are 5 directories each representing a liquid:
    PPE	  	(5-phenyl-4-ether)
    TPP		(triphenylphosphate)
    DBP		(dibutyl-phtalate)
    DEP		(diethyl-phtalate)
    epoxy	(2,3-epoxy propyl-phenyl-ether)
    
Each directory contains 2 files for each temperature step experiment:
     
   [name]_time_[T1]_to_[T2].dat	: the time in seconds
   [name]_IMeps_[T1]_to_[T2].dat: imaginary part of the dielectric
   				  constant at a fixed frequency 
				  (the frequency is indicated on the 
				  accompanying figure, and in the
				  original publication). 
 
Beside the data files, plots of the data exist as png and eps images for
reference.

NOTE: FIG.3(e) of the original publication showed incorrect temperatures. In the accompanying figures here this has been corrected.
