apply_smoothing_and_coord_transform(input_map, fwhm=None, rot=None, lmax=None, map_dist=None)¶
Apply smoothing and coordinate rotation to an input map
it applies the
healpy.smoothingGaussian smoothing kernel if
map_distis None, otherwise applies distributed smoothing with
libsharp. In the distributed case, no rotation is supported.
Input map, of shape
(3, npix)This is assumed to have no beam at this point, as the simulated small scale tempatle on which the simulations are based have no beam.
Full width at half-maximum, defining the Gaussian kernels to be applied.
- rot: hp.Rotator
Apply a coordinate rotation give a healpy
Rotator, e.g. if the inputs are in Galactic,
hp.Rotator(coord=("G", "C"))rotates to Equatorial
Array containing the smoothed sky
