In this comment line, the 11th field is described as the "Instrument" field. Here is an example:</div><div class=""><br class=""></div><div class=""><a href="http://service.iris.edu/fdsnws/station/1/query?net=TA&sta=MSTX&loc=--&cha=LHZ&level=channel&format=text&nodata=404" class="">http://service.iris.edu/fdsnws/station/1/query?net=TA&sta=MSTX&loc=--&cha=LHZ&level=channel&format=text&nodata=404</a></div><div class=""><br class=""></div><div class="">We are going to change this field in the header to "SensorDescription" to be more consistent with the examples in the specification. The header line is provided as a helpful guide and is not strictly needed for parsing the fixed-field data content. Nevertheless, someone might parsing this header.</div><div class=""><br class=""></div><div class="">If you will be effected by this change and cannot modify your usage to accommodate it quickly or easily please let us know so we can coordinate a time frame for the change. If we do hear from anyone the change will go into the next release, likely this week or next.</div><div class=""><br class=""></div><div class="">Chad</div></body></html>
