regrid_cube_hdu
(hdu, outheader, smooth=False, **kwargs)[source] [edit on github]¶ Regrid a FITS HDU to a target header. Requires that the FITS object and the target header have spectral and spatial overlap. See
regrid_cube
for additional details or alternative input options.Parameters: hdu :
PrimaryHDU
FITS HDU (not HDUlist) containing the cube to be reprojected
outheader :
Header
A target Header to project to
smooth : bool
Smooth the HDUs to match resolution? Kernel size is determined using
smoothing_kernel_size
Warning
Smoothing is done in 3D to be maximally general. This can be exceedingly slow!
Returns: rgcube :
PrimaryHDU
The regridded cube HDU
