Synopsis
Return the data used by plot_bkg_source.
Syntax
get_bkg_source_plot(id=None, lo=None, hi=None, bkg_id=None, recalc=True)
Examples
Example 1
Retrieve the source plot information for the background of the default data set and display it:
>>> splot = get_bkg_source_plot() >>> print(splot)
Example 2
Return the background plot data for data set 2, and then use it to create a plot:
>>> s2 = get_bkg_source_plot(2) >>> s2.plot()
Example 3
Create a plot of the first two background components of the 'histate' data set, overplotting the second on the first:
>>> b1 = get_bkg_source_plot('histate', bkg_id=1) >>> b2 = get_bkg_source_plot('histate', bkg_id=2) >>> b1.plot() >>> b2.overplot()
Example 4
Retrieve the background source plots for the 0.5 to 7 range of the 'jet' and 'core' data sets and display them on the same plot:
>>> splot1 = get_bkg_source_plot(id='jet', lo=0.5, hi=7) >>> splot2 = get_bkg_source_plot(id='core', lo=0.5, hi=7) >>> splot1.plot() >>> splot2.overplot()
Example 5
For a PHA data set, the units on both the X and Y axes of the plot are controlled by the `set_analysis` command. In this case the Y axis will be in units of photons/s/cm^2 and the X axis in keV:
>>> set_analysis('energy', factor=1) >>> splot = get_bkg_source_plot() >>> print(splot)
PARAMETERS
The parameters for this function are:
Parameter | Type information | Definition |
---|---|---|
id | int or str, optional | The data set that provides the data. If not given then the default identifier is used, as returned by `get_default_id` . |
lo | number, optional | The low value to plot. |
hi | number, optional | The high value to plot. |
bkg_id | int, str, or None, optional | Identify the background component to use, if there are multiple ones associated with the data set. |
recalc | bool, optional | If False then the results from the last call to `plot_bkg_source` (or `get_bkg_source_plot` ) are returned, otherwise the data is re-generated. |
Return value
The return value from this function is:
source -- An object representing the data used to create the plot by `plot_bkg_source` .
