function [ toaRelativeToPhaseRefTime ] = rawToa2PhaseRefTime(pFloatRfb)
%RAWTOA2PHASEREFTIME Converts the raw toa to travel time relative to phasereftime
%   Takes the raw toa given in the rfb file (travel time relative to window
%   start) and converts it to the travel time relative to the phasereftime.
%   
%   To convert it, it adds the windowstart offset to the raw toa. 
%   Parameters:
%       pFloatRfb (struct) The RFB file loaded using artoa.load.rfb function.
