Dataless SEED
What is a dataless SEED volume?
A dataless SEED volume contains the metadata for a request only, including
instrument responses, instrument coordinates, compression type, etc.. This
dataless volume can be used in combination with a miniSEED volume (as extracted
from the BUD filesystem) with rdseed.
A dataless, by definition, contains no "data", in the sense that
no waveform data are included, only headers.
Getting a Dataless SEED File:
1. Generate a request for a dataless using the online
form.
2. Submit a BREQ_FAST style request to dataless@iris.washington.edu from your
mail client.
3. Get a dataless from the BUD
Query Interface.
4. Download
network dataless SEED files from the IRIS
FTP site.
