<font size=2 face="sans-serif">Dear All,</font>
<br><font size=2 face="sans-serif"> in
a meeting about possible ECSS Adoption Notes for CCSDS docs to replace
some ECSSS standards, Marjorie de Lande Long has pointed out the following
difference between the two standards: </font>
<br><font size=2 face="sans-serif">R-S Berlecamp Annex, Table Equivalence
of Representations: ECSS underlines entries that correspond to values with
exactly one non-zero element and match a row in the matrix.</font>
<br>
<br><font size=2 face="sans-serif">I suggest that the C&S WG consider
in the next meeting whether modifying Annex F of CCSDS 131.0-B to use the
same approach of the ECSS book.</font>
<br><font size=2 face="sans-serif">Most likely, the change would be limited
to adding a note (like note b that you find in page 48 of the ECSS Standard)
and underlines the values to which this is applicable.</font>
<br>
<br><font size=2 face="sans-serif">To support the discussion I have uploaded
in CWE (Directory: The CCSDS Collaborative Work Environment (CWE) >
Space Link Services Area (SLS) > Documents > SLS-CandS > Meeting
Materials > 2015 > 2015_11 Darmstadt > CCSDS131.0-B.AnnexF ;

<br><font size=2 face="sans-serif">- The referenced standard: ECSS-E-ST-50-01C(31July2008).pdf</font>

<br><font size=2 face="sans-serif">Of course some material may even be
included in the Coding Green Book when an update will be done.</font>
