Hi all,
Using the obspy.iris Client I can get waveform data ok, and can also get
response info using client.saveResponse ( for both resp and sacpz formats ).
However if I use client.sacpz or client.resp then the same request fails - does anyone have any idea why ??
I think I’m using the latest available obspy.iris ( obspy.iris-0.5.0.dev_r3200 )
My code is as follows :
if name == ‘main’:
client = Client()
t1 = UTCDateTime(2002, 11, 3, 22, 20, 00, 000000)
t2 = UTCDateTime(2002, 11, 3, 22, 30, 00, 000000)
tr = client.getWaveform(“UW”,“LON”,’’,“BHZ”,t1,t2)
The above line works fine
t1 = UTCDateTime(“2002-11-01”)
t2 = UTCDateTime(“2003-01-01”)
available = client.availability(network=‘UW’,station=‘LON’,location=’’,channel=‘BHZ’,starttime=t1,endtime=t2)
print(available)
The above request works fine
outresp = ‘uw-lon.resp’
outsacpz = ‘uw-lon.sacpz’
client.saveResponse(outresp,network=‘UW’,station=‘LON’,location=’’,channel=‘BHZ’,starttime=t1,endtime=t2,format=“RESP”)
client.saveResponse(outsacpz,network=‘UW’,station=‘LON’,location=’’,channel=‘BHZ’,starttime=t1,endtime=t2,format=“SACPZ”)
The above two lines work fine
sacpz = client.sacpz(network=‘UW’,station=‘LON’,location=’’,channel=‘BHZ’,starttime=t1,endtime=t2)
print(sacpz)
The above client.sacpz fails, as does a similar client.resp request
Output & Error message from the ‘client.sacpz’ request is as follows :
UW LON – BHZ 2002-11-01T00:00:00 2003-01-01T00:00:00
