From these data sources, we have taken: all the nuclear magnitudes and total magnitudes observed at heliocentric distances r > 3 AU observed after 1950.
Some considerations are presented in Sect. 3.3
to justify the deletion of some data. Table 1 presents
a summary of the sources and a general classification of the data. The
numbers listed correspond to the data remaining after the deletions mentioned
in Sect. 3.3.
