 <p><h4>B - 5.5 RINEX Skeleton Extension - optional</h4></p>
 <p>
-BNC retrieves information needed for RINEX headers from so-called public RINEX header skeleton files as derived from sitelogs. An HTTP link to a directory containing these skeleton files may be available through data field number 7 of the affected NET record in the source-table. See <u>http://www.epncb.oma.be:80/stations/log/skl/BRUS.skl</u> for an example for a public RINEX header skeleton file concerning the EPN station Brussels.

-It may happen that public RINEX header skeleton files are not available, its contents is not up to date, or you need to have additional/optional records in the RINEX header. For that BNC lets you introduce personal skeleton files that contain the header records you would like to see. You may derive a personal RINEX header skeleton file from the information given in an up to date sitelog. A file in the 'RINEX directory' with the 'RINEX skeleton extension' is interpreted by BNC as a personal RINEX header skeleton file for the affected stream.
+Whenever BNC generates a new RINEX file, it first tries to retrieve information needed for RINEX headers from so-called public RINEX header skeleton files which are derived from sitelogs.
