get_FSF_from_cube_keywords
(cube, size)[source]¶ Return a cube of FSFs corresponding to the keywords presents in the MUSE data cube primary header (‘FSF***’)
The step of the FSF pixel is equal to the spatial step of the MUSE data cube. If the cube corresponds to mosaic of several fields (‘NFIELDS’>1), a list of FSF cubes is returned.
Parameters: cube :
mpdaf.obj.Cube
MUSE data cube
size : int
FSF size in pixels.
Returns: FSF : array (cube.shape[0], size, size) or list of arrays
Cube containing MUSE FSF (one per wavelength). One cube per field.
fwhm_pix : array(cube.shape[0]) or list of arrays
fwhm of the FSF in pixels
fwhm_arcsec : array(cube.shape[0]) or list of arrays
fwhm of the FSF in arcsec
