 As we can see, mass_1, t_zero, dec are not estimated very well, whose truths are on the edge.

+## (15)VItamin: Korean BBH waveform test   
+For Korean waveform, signal is generated with points less than 256. We need to pad it to 256 as VItamin requires. I pad it on the back because start time is already set when generating signal.  
+Next is to find t_zero's value.

+t_zero = t_peak - ref_geocent_time.(Is that right?)    
+Then we get t_zero's truth.

+I generate 4 samples for this test. Plots above are of the first one. As we can see, theta_jn and ra are totally wrong. Other parameters are good. Furthermore, theta_jn and ra also get a bad estimation in other 3 samples.
