Module convolve_uv 

FFT-based UV-plane beam convolution.

This is a port of racs_tools.convolve_uv.convolve and racs_tools.gaussft.gaussft. The “robust” mode is implemented: the FT of the convolving Gaussian is computed analytically at each UV point (no kernel image needed), which handles NaNs gracefully.

Functions

convolve_uv

Convolve image from old_beam to new_beam in the UV plane.

fftfreq

numpy-compatible fftfreq(n, d).

gaussft

Compute the UV-plane filter that deconvolves old_beam and re-convolves with new_beam. Direct port of racs_tools.gaussft.gaussft.
