Thirdly, when the :END_FREQ_S is written to, the step
is updated:
| Mathinline |
|---|
| body | \delta \leftarrow (e-s)/N |
|---|
|
. Finally, the range of valid values for each field is different:
is unsigned,
is signed,
is signed and unbounded. This is summarised in the table below (here
is the number of bunches per machine revolution).
