# set_dep¶

sherpa.astro.ui.set_dep(id, val=None, bkg_id=None)

Set the dependent axis of a data set.

Parameters
• 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 values for the dependent axis.

• 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.

dataspace1d()

Create the independent axis for a 1D data set.

dataspace2d()

Create the independent axis for a 2D data set.

get_dep()

Return the dependent axis of a data set.

load_arrays()

Create a data set from array values.

Notes

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.

Examples

Create a 1D data set with values at (0,4), (2,10), (4,12), (6,8), (8,2), and (10,12):

>>> dataspace1d(0, 10, 2, dstype=Data1D)
>>> set_dep([4, 10, 12, 8, 2, 12])


Set the values for the source and background of the data set ‘src’:

>>> set_dep('src', y1)
>>> set_dep('src', bg1, bkg_id=1)
