     682GNSS observation data are generally hold available by BNC according to attributes defined in RINEX Version 3. These attributes describe the tracking mode or channel of observations. Capital letters specifying observation attributes are C, D, I, L, M, P, Q, S, W, X, Y, and N, see RINEX Version 3 documentation.
     683</p>
     684<p>There are two applications where BNC can output observation data following RINEX Version 2:
     685<ul>
     686<li>
     687Saving incoming observation streams in RINEX Version 2 format.
     688</li>
     689<li>
     690'Edit/Concatenate' RINEX 3 files and save them in Version 2 format.
     691</li>
     692</ul>
     693As the Version 2 format ignores observation attributes, BNC is forced to map RINEX Version 3 to RINEX Version 2 although this can't be done in one-to-one correspondance. Hence we introduce a priority list of attributes for mapping Version 3 to Version 2.
     694</p>
     695<p>
     696The default priority list is an empty option string meaing a priority of 'CWPX_?' attributes when mapping RINEX 3 to RINEX 2. (Noch nicht fertig.)

    681701The default format for RINEX Observation files is RINEX Version 2.11. Select 'Version 3' if you would like to save observations in RINEX Version 3 format.
