calc_feed_rotation

pyvisgen.simulation.scan.calc_feed_rotation(X1: tensor, X2: tensor, bas, polarization: str) → tuple[tensor, tensor]

Calculates the feed rotation due to the parallactic angle rotation of the source over time.

Parameters:

X1tensor()

Fourier kernel calculated via calc_fourier().

X2tensor()

Fourier kernel calculated via calc_fourier().

basValidBaselineSubset

Baselines dataclass object containing information on u, v, and w coverage, observation times, and parallactic angles.

polarizationstr

Type of polarization for the feed.

Returns:

X1tensor()

Fourier kernel with the applied feed rotation.

X2tensor()

Fourier kernel with the applied feed rotation.
