set_dep
- sherpa.astro.ui.set_dep(id, val=None, bkg_id: IdType | None = None) 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.

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 theid
andval
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)
