block_effelsberg

pyoof.telgeometry.block_effelsberg(x, y)

Truncation in the aperture (amplitude) distribution, \(B(x, y)\), given by the telescope’s structure; i.e. support legs, sub-reflector and shade effect as seen from the secondary focus of the Effelsberg telescope.

Parameters:

x : ndarray

Grid value for the \(x\) variable in meters.

y : ndarray

Grid value for the \(y\) variable in meters.

Returns:

block : ndarray

Aperture (amplitude) distribution truncation, \(B(x, y)\). Values that are zero correspond to blocked values.
