Suslin number vs cellularity

The text currently states The Suslin number of a topological space X is the minimum cardinal number κ such that every pairwise disjoint family of open subsets of X has cardinality less than κ: cf. Cardinal characteristic. This is closely related to the cellularity: the supremum of the cardinalities of pairwise disjoint families of open subsets. Yet the article Cardinal characteristic states that The Suslin number of a space is also called its cellularity and this is supported by modern references. It also seems to be what the text is saying. What is the difference, if any? Richard Pinch (talk) 20:07, 19 December 2015 (CET)
