edges_analysis.calibration.loss.ground_loss(filename: str | Path, freq: ndarray, beam=None, deg_step: float = 1.0, band: str | None = None, configuration: str = '') → ndarray[source]

Calculate ground loss of a particular antenna at given frequencies.

Parameters:

  • filename (path) – File in which value of the ground loss for this instrument are tabulated.

  • freq (array-like) – Frequency in MHz. For mid-band (low-band), between 50 and 150 (120) MHz.

  • beam – A Beam instance with which the ground loss may be computed.

  • deg_step – The steps (in degrees) of the azimuth angle in the beam (if given).

  • band (str, optional) – The instrument to find the ground loss for. Only required if filename doesn’t exist and isn’t an absolute path (in which case the standard directory structure will be searched using band).

  • configuration (str, optional) – The configuration of the instrument. A string, such as “45deg”, which defines the orientation or other configuration parameters of the instrument, which may affect the ground loss.
