[Access to the data]

〓 Question No.15   2006/02/22
Why does my downloaded file have an extension of "tar.tar"? I selected the compression type, "tar+compress" or "tar+gzip".

〓 Question No.14   2005/03/31
How can I get user account for getting data?

〓 Question No.09   2000/12/22
When I want to get the waveform from 2000/01/01,00:00:00 to 2000/01/01,00:10:00, does the following command work?
get [station name] [component name] 00/01/01,00:00:00 00/01/01,00:10:00


〓 Question No.01   2000/04/07
How can I get waveform data from you?


[Waveform data]

〓 Question No.20   2008/06/10
How can I use the SAC?

〓 Question No.03   2007/11/08
What is the " TEXT Format "?

〓 Question No.08   2000/09/25
Are broadband waveforms provided by the F-net project already corrected for the instrumental response?
Or should I remove instrumental response from the waveforms obtained?

〓 Question No.05   2000/08/09
Where can I find the scale factor of the data (in text format)?
It is not included in the heading of the blocks.

〓 Question No.06   2000/08/09
Some records of the broadband data are all negative. What does it mean.
Is any shift required in the axis.

〓 Question No.04   2000/06/05
Why does the SAC data header have non-zero NZMSEC field? Is it observed value or useless one? These values are different among stations.
Moreover, is it possible to specify the time window in mili-seconds?
