set_filter(id, val=None, bkg_id=None, ignore=False)¶
Set the filter array of a data set.
id (int or str, optional) – The data set to use. If not given then the default identifier is used, as returned by get_default_id.
val (array) – The array of filter values (
1). The size should match the array returned by get_dep.
bkg_id (int or str, optional) – Set to identify which background component to set. The default value (
None) means that this is for the source component of the data set.
ignore (bool, optional) – If
False(the default) then include bins with a non-zero filter value, otherwise exclude these bins.
The function does not follow the normal Python standards for parameter use, since it is designed for easy interactive use. When called with a single un-named argument, it is taken to be the val parameter. If given two un-named arguments, then they are interpreted as the id and val parameters, respectively.
Ignore those bins with a value less 20.
>>> d = get_dep() >>> set_filter(d >= 20)
