subtract_psf¶
- photutils.psf.subtract_psf(data, psf, posflux, *, subshape=None)[source]¶
Deprecated since version 1.9.0: The subtract_psf function is deprecated and may be removed in a future version.
Subtract PSF/PRFs from an image.
- Parameters:
- data
NDData
or array (must be 2D) Image data.
- psf
astropy.modeling.Fittable2DModel
instance PSF/PRF model to be subtracted from the data.
- posfluxArray-like of shape (3, N) or
Table
Positions and fluxes for the objects to subtract. If an array, it is interpreted as
(x, y, flux)
If a table, the columns ‘x_fit’, ‘y_fit’, and ‘flux_fit’ must be present.- subshapelength-2 or None
The shape of the region around the center of the location to subtract the PSF from. If None, subtract from the whole image.
- data
- Returns:
- subdatasame shape and type as
data
The image with the PSF subtracted.
