  In [11] and [13] the authors showed that elementary cellular automata rules
0, 3, 8, 12, 15, 28, 32, 34, 44, 51, 60, 128, 136, 140, 160, 162, 170, 200 and
204 (and their conjugation, reflection, reflected-conjugation) are not maximum
sensitive to synchronism, i.e. they do not have a different dynamics for each
(non-equivalent) block-sequential update schedule (defined as ordered
partitions of cell positions). In this work we present exact measurements of
the sensitivity to synchronism for these rules, as functions of the size. These
exhibit a surprising variety of values and associated proof methods, such as
the special pairs of rule 128, and the connection to the bissection of Lucas
numbers of rule 8.
