Methods

LineShapeOutput(self, line: int, T: float, P: float, VMR: pyarts.arts.Vector) → pyarts.arts.LineShapeOutput

Computes the line shape paramters for the given atmospheric state

Note that the normalization assumes sum(VMR) is 1 for good results but does not enforce it

Parameters:

• line (int) – Line index

• T (float) – Temperature

• P (float) – Pressure

• VMR (Vector) – List of VMR values, must match length of broadening species

Returns:

X – The computed line shape parameters

Return type:

LineShapeOutput

readxml(self, file: str) → None

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) → None

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 (ascii. zascii, or binary)

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

On Error:

Throws RuntimeError for any failure to save

Static Methods

fromxml(file: str) → pyarts.arts.AbsorptionLines

Create variable from file

Parameters:

file (str) – A file that can be read

On Error:

Throws RuntimeError for any failure to read
