Returns new Stream object cut to the given start- and endtime.
Parameters: |
|
---|---|
Returns: |
Note
The basic idea of slice() is to avoid copying the sample data in memory. So sample data in the resulting Stream object contains only a reference to the original traces.
Example
>>> st = read()
>>> print(st)
3 Trace(s) in Stream:
BW.RJOB..EHZ | 2009-08-24T00:20:03.000000Z ... | 100.0 Hz, 3000 samples
BW.RJOB..EHN | 2009-08-24T00:20:03.000000Z ... | 100.0 Hz, 3000 samples
BW.RJOB..EHE | 2009-08-24T00:20:03.000000Z ... | 100.0 Hz, 3000 samples
>>> dt = UTCDateTime("2009-08-24T00:20:20")
>>> st = st.slice(dt, dt + 5)
>>> print(st)
3 Trace(s) in Stream:
