Synopsis
Plot the 1D PSF model applied to a data set.
Syntax
plot_psf(id=None, replot=False, overplot=False, clearwindow=True, **kwargs) id - int or str, optional replot - bool, optional overplot - bool, optional clearwindow - bool, optional
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 | Definition |
|---|---|
| id | The data set. If not given then the default identifier is used, as returned by `get_default_id` . |
| replot | Set to True to use the values calculated by the last call to `plot_psf` . The default is False . |
| overplot | If True then add the data to an existing plot, otherwise create a new plot. The default is False . |
| clearwindow | Should the existing plot area be cleared before creating this new plot (e.g. for multi-panel plots)? |
