get_psf

Context: psfs

Synopsis

Return the PSF model defined for a data set.

Syntax

get_psf(id=None)

id - int or str, optional

Description

Return the parameter settings for the PSF model assigned to the data set.


Example

Change the size and center of the PSF for the default data set:

>>> psf = get_psf()
>>> psf.size = (21, 21)
>>> psf.center = (10, 10)

PARAMETERS

The parameter for this function is:

Parameter Definition
id The data set. If not given then the default identifier is used, as returned by `get_default_id` .
