'Have been for years. Your webicorders seem to have an inconsistency in their measurement. Is there a procedure for setting the noise floor for baseline measurements? Does this entail adjusting analog to digital converters. (Burr Brown maybe?) Just curious. Katmai shows readings off the wall. Augustine and Redoubt have a nice noise floor bias whereas Fourpeaked has a flat line. ...Hmm? ---------------------------------------------------------------- REMOTE IP ADDRESS: 127.0.0.1 USER AGENT/BROWSER: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/534.57.2 (KHTML, like Gecko) Version/5.1.7 Safari/534.57.2 REFERRING PAGE: http://www.avo.alaska.edu/contact.php
