Methods

clear(self) → None

Remove all items

clear_linemixing(self) → int

Clear the linemixing data from all bands by removing it from the inner line shape models

Returns:

int

Return type:

The number of removed variables

count_lines(self, spec: pyarts.arts.SpeciesEnum = 'AIR') → int

Return the total number of lines

items(self) → pyarts.arts.AbsorptionBands.ItemView

Returns an iterable view of the map’s items.

keep_hitran_s(self, approximate_percentile: float | collections.abc.Mapping[pyarts.arts.SpeciesEnum, float], T0: float = 296.0) → None

Wraps calling percentile_hitran_s followed by remove_hitran_s.

Parameters:

• percentile (float or dict) – See percentile_hitran_s.

• T0 (float) – The reference temperature. Defaults to 296.0.

keys(self) → pyarts.arts.AbsorptionBands.KeyView

Returns an iterable view of the map’s keys.

merge(self, other: pyarts.arts.AbsorptionBands) → tuple[int, int]

Merge the other absorption bands into this

If the key in the other absorption bands already exists in this, the lines with the same local quantum numbers are overwritten by those of the other absorption bands.

Parameters:

other (AbsorptionBands) – The other absorption bands to merge into this

percentile_hitran_s(self, approximate_percentile: float | collections.abc.Mapping[pyarts.arts.SpeciesEnum, float], T0: float = 296.0) → dict[pyarts.arts.SpeciesEnum, float]

Map of HITRAN linestrengths at a given percentile

Note

The percentile is approximated by floating point arithmetic on the sorted HITRAN line strenght values.

Parameters:

• percentile (float or dict) – The percentile to keep. If a float, the same percentile is used for all species. If a dict, the species are mapped to their respective percentiles. Values must be [0, 100].

• T0 (float) – The reference temperature. Defaults to 296.0.

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

remove_hitran_s(self, remove: collections.abc.Mapping[pyarts.arts.SpeciesEnum, float], T0: float = 296.0) → None

Removes all lines with a weaker HITRAN-like line strength than those provided by the remove map.

Parameters:

• remove (dict) – The species to keep with their respective minimum HITRAN-like line strengths

• T0 (float) – The reference temperature. Defaults to 296.0.

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. 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

update(self, arg: pyarts.arts.AbsorptionBands, /) → None

Update the map with element from arg

values(self) → pyarts.arts.AbsorptionBands.ValueView

Returns an iterable view of the map’s values.

Static Methods

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

Create variable from file

Parameters:

file (str) – A file that can be read

On Error:

Throws RuntimeError for any failure to read
