Dear SAC-users:<br>I am using SAC for seismological analysis recently.
However, I got some problem about HYPO format using OHPF with sac101.4. I piked/marked the phase after opening the OHPF and OAPF, but the result is different as follows:<br> <br>case1: GJM IPU0 11 3 9 24663.00 0 0.0 (OHPF)<br>
case2: -12345 GJM 90.00 90.00IPU0 2011 68 2 46 2.06 -4171 M (OAPF)<br><br>In
case1 the second of the P arrival is 63.00, while in case2 that is
2.06. What does the last four digits(e.g. 63.00) mean? Does it mean the
arrival of the P arrival, and if that, why is it different from the
result in case2?<br>
<br>Please help me about that.<br>Thanks<br><br>Xin Zhang<br><br>
