Synopsis
Plot the 1D PSF model applied to a data set.
Syntax
plot_psf(id=None, replot=False, overplot=False, clearwindow=True, **kwargs)
Description
The `plot_kernel` function shows the data used to convolve the model.
Example
Create a model (a step function) that is convolved by a gaussian, and display the PSF:
>>> dataspace1d(1, 10, step=1, dstype=Data1D)
>>> set_model(steplo1d.stp)
>>> stp.xcut = 4.4
>>> load_psf('psf1', gauss1d.gline)
>>> set_psf('psf1')
>>> gline.fwhm = 1.2
>>> plot_psf()PARAMETERS
The parameters for this function are:
| Parameter | Type information | Definition |
|---|---|---|
| id | int, str, or None, optional | The data set. 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 `plot_psf` . The default is False . |
| overplot | bool, optional | If True then add the data to an existing plot, otherwise create a new plot. The default is False . |
| clearwindow | bool, optional | Should the existing plot area be cleared before creating this new plot (e.g. for multi-panel plots)? |
