SensorObsel

class pyarts3.arts.SensorObsel(*args, **kwargs)

A single observation element.

This should result in a single element in a measurement_vector.

Expected use of this type is to generate the measurement vector of a sensor, where this observation element represent the readout from that sensor in a convenient unit (commonly Kelvin or W sr \(^{-1}\) m \(^{-2}\) Hz \(^{-1}\), but not exclusively)

It deals with averaging the frequency grid sampled by a sensor element and the transmission of the sensor system onto the sampling device, as well as the sampling device’s polarization response.

Note

Multiple SensorObsel can be used to represent a single sensor with multiple channels, such as a sensor with multiple detectors or a sensor with multiple frequency channels. They then can conveniently share much of their grids, but have different weighting functions and/or different sampling devices.

Methods

readxml(self, file: str) → str

Read variable from file

Parameters:

file (str) – A file that can be read

On Error:

Throws RuntimeError for any failure to read

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) – Type of file to save. See FileType for options.

• clobber (bool) – Overwrite existing files or add new file with modified name?

On Error:

Throws RuntimeError for any failure to save
