notice_id

sherpa.ui.notice_id(ids, lo=None, hi=None, **kwargs)

Include data from the fit for a data set.

Select one or more ranges of data to include by filtering on the independent axis value. The filter is applied to the given data set, or data sets.

Parameters

  • 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 :b means include everything up to, and including b, and a: means inlude everything that is higher than, or equal to, a.

  • hi (number, optional) – The upper bound of the filter when lo is 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_id is 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.

Exclude data from the fit for a data set.

sherpa.astro.ui.ignore2d

Exclude a spatial region from an image.

notice

Include data in the fit.

show_filter

Show any filters applied to a data set.

Notes

The order of ignore and notice calls is important.

The units used depend on the analysis setting of the data set, if appropriate.

To filter a 2D data set by a shape use ignore2d.

Examples

Include all data points with an X value (the independent axis) between 12 and 18 for data set 1:

>>> notice_id(1, 12, 18)

Include the range 0.5 to 7, for data sets 1, 2, and 3:

>>> notice_id([1,2,3], 0.5, 7)

Apply the filter 0.5 to 2 and 2.2 to 7 to the data sets “core” and “jet”:

>>> notice_id(["core","jet"], "0.5:2, 2.2:7")
