Computati<strong>on</strong> of P-wave arrival time delays and<br />
relative amplitude of the initial P-waves carried<br />
out w.r.t. Pe03 reference stati<strong>on</strong><br />
C<strong>on</strong>sidering P-wave <strong>on</strong>ly in to account, the<br />
unprocessed teleseismic signal is bandpass filtered<br />
between 0.2 – 1.0 Hz, as per S/N ratio in<br />
relatively shorter window length<br />
P-wave time delays are carefully determined by<br />
cross-correlating the first quarter-cycle of the<br />
initial P-waveform of each stati<strong>on</strong> w.r.t. Pe03<br />
reference stati<strong>on</strong><br />
Also the amplitude ratio of the first P-wave<br />
arrivals are determined w.r.t. refrence stati<strong>on</strong>
