    1534 Default 'Signal priority' list is an empty option string, meaning a priority sequence of 'CWPX_?' attributes when mapping RINEX 3 to RINEX 2. The meaning of this sequence of characters - take it as an example - is as follows:
     1534Signal priorities can be specified as equal for all systems, as system specific or as system and frequency specific. For example:</li>
     1535<ul>
     1536<li>'CWPX_?' (General signal priorities valid for all GNSS)</li>
     1537<li>'C:IQX I:ABCX' (System specific signal priorities for BDS and IRNSS)</li>
     1538<li>'G:12&PWCSLXYN G:5&IQX R:12&PC R:3&IQX' (System and frequency specific signal priorities)</li>
     1539</ul>
     1540</p>
     1541<p>
     1542The default 'Signal priority' list is defined as follows:
     1543<ul>
     1544 <li>'G:12&PWCSLXYN G:5&IQX R:12&PC R:3&IQX E:16&BCX E:578&IQX J:1&SLXCZ J:26&SLX J:5&IQX C:IQX I:ABCX S:1&C S:5&IQX'</li>
     1545</ul>
     1546
     1547As an example the 'Signal priority' of 'CWPX_?' is explained in more detail:
    15351548<ul>
    15361549<li>Signals with attribute 'C' enjoy the highest priority. If such a Version 3 observation becomes available, it is presented as RINEX Version 2 observation if that is the format you wish to see. Observations with other attributes are being ignored.</li>
     
    15411554</p>
    15421555
    1543 <p>
    1544 Signal priorities can be specified either as equal for all systems or system specific. The following are example priority strings:</li>
    1545 <ul>
    1546 <li>CWPX_? (Same signal priorities valid for all systems)</li>
    1547 <li>G:CWPX_? R:PCX_? E:CPX_? (Specific signal priorities for GPS, GLONASS and Galileo system)</li>
    1548 </ul>
    1549 
    1550 </p>
    15511556<p>
    15521557You may like to specify your own 'Signal priority' string(s) for producing RINEX Version 2 files. If you neither convert observation streams to RINEX Version 2 nor concatenate RINEX Version 3 to Version 2 files, then the 'Version 2' option is meaningless.
