function val = get(c,prop_name)
   
   % GET - Get correlation properties
   %
   % VAL = get(C,PROP_NAME)
   % See HELP CORRELATION for description of primary property names:
   %   Waveforms, Trig, Corr, Lag, Stat, Link, Clust
   %
   % Additional scalar properties:
   %   Traces:         number of traces
   %   Data_Length:    number of samples in each trace
   %   Fs:             Frequency
   %   Period:         Period
   %   Nyq:            Nyquist frequency
   %   **NOTE - The scalar properties listed above exist for each waveform
   %   (except Traces). However, the correlation object requires them to be
   %   the same. GET only reads the value associated with the first waveform
   %   Normally this will not be an issue. If the correlation object
   %   was created manually it is possible for these fields to be different.
   %
   % Additional vector properties (nx1):
   %   Start, Trig, End:             same as Start_Matlab, End_Matlab
   %   Start_Str, Trig_Str, End_Str:           String times
   %   Start_Matlab, Trig_Matlab, End_Matlab:  Matlab-format times
   %   Start_Epoch, Trig_Epoch, End_Epoch:     Epoch-format times
   %
   % Additional vector properties (nx1 cell vector)
   %   Sta (or Station):       Cell vector of station names
   %   Chan (or Component):    Cell vector of channel names
   %
   % Additional matrix properties (nxm matrix)
   %   Data:                    Matrix of raw trace data
   %                           (n traces) x (m samples)
