Synopsis
Contour the residuals of the fit.
Syntax
contour_resid(id=None, replot=False, overcontour=False, **kwargs)
Description
The residuals are formed by subtracting the current model - including any PSF - from the data. The preferences are the same as `contour_data` .
Examples
Example 1
Plot the residuals from the default data set:
>>> contour_resid()
Example 2
Overplot the residuals on the model:
>>> contour_model('img')
>>> contour_resid('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_resid` . 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 . |
