# cfdm.core.Bounds¶

class cfdm.core.Bounds(properties=None, data=None, source=None, copy=True, _use_data=True)[source]

Bases: cfdm.core.abstract.propertiesdata.PropertiesData

A cell bounds component.

That is, a cell bounds component of a coordinate or domain ancillary construct of the CF data model.

An array of cell bounds spans the same domain axes as its coordinate array, with the addition of an extra dimension whose size is that of the number of vertices of each cell. This extra dimension does not correspond to a domain axis construct since it does not relate to an independent axis of the domain. Note that, for climatological time axes, the bounds are interpreted in a special way indicated by the cell method constructs.

New in version (cfdm): 1.7.0

Initialisation

Parameters
properties: dict, optional

Set descriptive properties. The dictionary keys are property names, with corresponding values.

Properties may also be set after initialisation with the set_properties and set_property methods.

Parameter example:

properties={'standard_name': 'longitude'}

data: data_like, optional

Set the data.

A data_like object is any object that can be converted to a Data object, i.e. numpy array_like objects, Data objects, and cfdm.core instances that contain Data objects.

The data also may be set after initialisation with the set_data method.

source: optional

Convert source, which can be any type of object, to a Bounds instance.

All other parameters, apart from copy, are ignored and their values are instead inferred from source by assuming that it has the Bounds API. Any parameters that can not be retrieved from source in this way are assumed to have their default value.

Note that if x is also a Bounds instance then cfdm.core.Bounds(source=x) is equivalent to x.copy().

copy: bool, optional

If True (the default) then deep copy the input parameters prior to initialisation. By default the parameters are not deep copied.
