Abstract
Given a cofinal cardinal function for inaccessible, we consider the dominating -localisation number, that is, the least cardinality of a dominating set of -slaloms such that every -real is localised by a slalom in the dominating set. It was proved in arXiv:1611.08140 that the dominating localisation numbers can be consistently different for two functions (the identity function and the power function). We will construct a -sized family of functions and their corresponding localisation numbers, and use a -supported product of a cofinality-preserving forcing to prove that any simultaneous assignment of these localisation numbers to cardinals above is consistent. This answers an open question from arXiv:1611.08140 .
