The column headed Des is the half month or other designation of the comet. The column headed C gives the SOHO instrument (C2 or C3 for the LASCO coronagraphs, SW for SWAN, T1 or T2 for STEREO) that the comet was discovered in. The column headed G indicates if it is a provisional member of the Kreutz group (K), Meyer group (Y), Marsden group (D), Kracht (R) or other comet (O). P in the SOHO number column indicates the discovery is pending, C indicates that it is confirmed, but not yet numbered, U indicates that is was not confirmed, X that it was confirmed, but there were insufficient observations.

Note that my observer count also includes X/ comets which are not counted as confirmed comets by the SOHO team. Where two or more people report discoveries nearly simultaneously, up to the first three observers are credited here. Where discoverers are clearly not following the SOHO or BAA Comet Section guidelines, they are not credited here at all. If initial reports don't include sufficient positions others may also be credited.

It is possible that there are further comets to be found in the archival data, most likely non-group comets, but there may still be some Kreutz comets.
