Hi,<br class="">
<br class="">
The following gives nothing in my browser (no error, no change of
page...):<br class="">
<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://service.iris.edu/fdsnws/station/1/query?net=II&sta=AAK&loc=--&cha=BHZ&starttime=1992-12-12&endtime=1992-12-12&level=station">http://service.iris.edu/fdsnws/station/1/query?net=II&sta=AAK&loc=--&cha=BHZ&starttime=1992-12-12&endtime=1992-12-12&level=station</a><br class="">
<br class="">
If I remove the loc=--, it works fine:<br class="">
<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://service.iris.edu/fdsnws/station/1/query?net=II&sta=AAK&cha=BHZ&starttime=1992-12-12&endtime=1992-12-12&level=station">http://service.iris.edu/fdsnws/station/1/query?net=II&sta=AAK&cha=BHZ&starttime=1992-12-12&endtime=1992-12-12&level=station</a><br class="">
<br class="">
Doc says:<br class="">
loc[ation] 00 Select one or more SEED location identifier.
Use -- for “Blank” location IDs (ID’s containing 2 spaces).
Accepts wildcards and lists. Accepts exclusions.<br class="">
<br class="">
Am I missing something?<br class="">
<br class="">
Thanks,<br class="">
