Synopsis
Contour the ratio of data to model.
Syntax
contour_ratio(id=None, replot=False, overcontour=False, **kwargs)
Description
The ratio image is formed by dividing the data by the current model, including any PSF. The preferences are the same as `contour_data` .
Examples
Example 1
Plot the ratio from the default data set:
>>> contour_ratio()
Example 2
Overplot the ratio on the residuals:
>>> contour_resid('img')
>>> contour_ratio('img', overcontour=True)PARAMETERS
The parameters for this function are:
| Parameter | Type information | Definition |
|---|---|---|
| id | int, str, or None, optional | The data set that provides the data and model. If not given then the default identifier is used, as returned by `get_default_id` . |
| replot | bool, optional | Set to True to use the values calculated by the last call to `contour_ratio` . The default is False . |
| overcontour | bool, optional | If True then add the data to an existing plot, otherwise create a new contour plot. The default is False . |
