Data extraction issue for 8H and 9H networks

[Rinku-274]

I am experiencing an issue with Pysep while downloading data for stations in the 8H and 9H networks. Despite setting seconds_before_ref: 100 and seconds_after_ref: 300 in the .yaml file, the extracted data starts earlier than -100 seconds from the reference time. Additionally, when viewed in SAC, the event appears to occur before the origin time for some stations, which is incorrect.

This problem is specific to the 8H and 9H networks, while other stations behave as expected. The input DOC
file and SAC output image for a particular station are attached.

Hi @Rinku-274, thanks for bringing this issue. It's slightly concerning that this is happening only for certain networks while other stations are behaving as expected, that makes me think it's a data/metadata issue for 8H and 9H networks, rather than a PySEP issue, since some things are working as expected. Is there any information in the log file that suggests PySEP is shifting the origin time? Also can you point me towards a specific station where this is working? It would be useful to see the comparison between them.
