Reading

There are three types of ALSEP tape: PSE, WTN, and WTH. They are handled by using ObsPy’s standard:func:~obspy.core.stream.read function. The format is detected automatically.

>>> from obspy import read
>>> url = "http://darts.isas.jaxa.jp/pub/apollo/pse/p15s/pse.a15.1.2"
>>> st = read(url)  
>>> st  
<obspy.core.stream.Stream object at 0x...>
>>> st_spz = st.select(id='XA.S15..SPZ')  
>>> print(st_spz)
