Constructors

__init__(self, grid: pyarts3.arts.ZenGrid, aperture_diameter: float, azi_grid_size: int = 2, weight: pyarts3.arts.Stokvec = [1, 0, 0, 0]) → None

__init__(self) → None

__init__(self, arg: pyarts3.arts.sensor.GaussianAiryAntenna) → None

Overloaded function.

__init__(self, grid: pyarts3.arts.ZenGrid, aperture_diameter: float, azi_grid_size: int = 2, weight: pyarts3.arts.Stokvec = [1, 0, 0, 0]) -> None

Construct a Gaussian Airy antenna on the supplied local grids. The channel frequency grid must be strictly positive because the current builder path does not carry a separate reference frequency.

Methods

readxml(self, file: str) → str

Read variable from file.

Parameters:: file (str) – A file that can be read.
Raises:: RuntimeError – For any failure to read.
Returns:: file – The file path found (may differ from input due to environment variables).
Return type:: str

savexml(self, file: str, type: str = 'ascii', clobber: bool = True) → str

Saves variable to file.

Parameters:

file (str) – The path to which the file is written. Note that several of the options might modify the name or write more files.
type (str, optional) – Type of file to save. See FileType for options. Defaults is “ascii”.
clobber (bool, optional) – Overwrite existing files or add new file with modified name? Defaults is True.

Raises:

RuntimeError – For any failure to write.

Returns:

file – The file saved. May differ from input.

Return type:

str

std(self, arg: object, /) → object: Standard deviation of the antenna response at a given frequency.

Static Methods

fromxml(file: str) → pyarts3.arts.sensor.GaussianAiryAntenna

Create variable from file.

Parameters:: file (str) – A file that can be read
Raises:: RuntimeError – For any failure to read.
Returns:: artstype – The variable created from the file.
Return type:: T
