ignore_id(ids, lo=None, hi=None, **kwargs)¶
Exclude data from the fit for a data set.
Select one or more ranges of data to exclude by filtering on the independent axis value. The filter is applied to the given data set, or sets.
ids (int or str, or array of int or str) – The data set, or sets, to use.
lo (number or str, optional) – The lower bound of the filter (when a number) or a string expression listing ranges in the form
a:b, with multiple ranges allowed, where the ranges are separated by a
,. The term
:bmeans exclude everything up to, and including
a:means exclude everything that is higher than, or equal to,
hi (number, optional) – The upper bound of the filter when
lois not a string.
bkg_id (int or str, optional) – The filter will be applied to the associated background component of the data set if
bkg_idis set. Only PHA data sets support this option; if not given, then the filter is applied to all background components as well as the source data.
The order of ignore and notice calls is important.
The units used depend on the
analysissetting of the data set, if appropriate.
To filter a 2D data set by a shape use ignore2d.
Ignore all data points with an X value (the independent axis) between 12 and 18 for data set 1:
>>> ignore_id(1, 12, 18)
Ignore the range up to 0.5 and 7 and above, for data sets 1, 2, and 3:
>>> ignore_id([1,2,3], None, 0.5) >>> ignore_id([1,2,3], 7, None)
Apply the same filter as the previous example, but to data sets “core” and “jet”:
>>> ignore_id(["core","jet"], ":0.5,7:")
