add_deprecated_field(name, function, sampling_type, since, removal=None, ret_name=None, **kwargs)

Add a new field which is deprecated, along with supplemental metadata, to the list of available fields. This respects a number of arguments, all of which are passed on to the constructor for DerivedField.

Parameters:

• name (str) – is the name of the field.

• function (callable) – A function handle that defines the field. Should accept arguments (field, data)

• sampling_type (str) – “cell” or “particle” or “local”

• since (str) – The version string marking when this field was deprecated.

• removal (str) – The version string marking when this field will be removed.

• ret_name (str) – The name of the field which will actually be returned, used only by alias().

• units (str) – A plain text string encoding the unit. Powers must be in python syntax (** instead of ^). If set to “auto” the units will be inferred from the return value of the field function.

• take_log (bool) – Describes whether the field should be logged

If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

add_deprecated_field(name, function, sampling_type, since, removal=None, ret_name=None, **kwargs)

Add a new field which is deprecated, along with supplemental metadata, to the list of available fields. This respects a number of arguments, all of which are passed on to the constructor for DerivedField.

Parameters:

• name (str) – is the name of the field.

• function (callable) – A function handle that defines the field. Should accept arguments (field, data)

• sampling_type (str) – “cell” or “particle” or “local”

• since (str) – The version string marking when this field was deprecated.

• removal (str) – The version string marking when this field will be removed.

• ret_name (str) – The name of the field which will actually be returned, used only by alias().

• units (str) – A plain text string encoding the unit. Powers must be in python syntax (** instead of ^). If set to “auto” the units will be inferred from the return value of the field function.

• take_log (bool) – Describes whether the field should be logged

• validators (list) – A list of FieldValidator objects

• vector_field (bool) – Describes the dimensionality of the field. Currently unused.

• display_name (str) – A name used in the plots

add_field(name: tuple[str, str], function: Callable, sampling_type: str, *, alias: DerivedField | None = None, force_override: bool = False, **kwargs) → None

Add a new field, along with supplemental metadata, to the list of available fields. This respects a number of arguments, all of which are passed on to the constructor for DerivedField.

Parameters:

• name (tuple[str, str]) – field (or particle) type, field name

• function (callable) – A function handle that defines the field. Should accept arguments (field, data)

• sampling_type (str) – “cell” or “particle” or “local”

• force_override (bool) – If False (default), an error will be raised if a field of the same name already exists.

• alias (DerivedField (optional):) – existing field to be aliased

• units (str) – A plain text string encoding the unit. Powers must be in python syntax (** instead of ^). If set to “auto” the units will be inferred from the return value of the field function.

• take_log (bool) – Describes whether the field should be logged

• validators (list) – A list of FieldValidator objects

• vector_field (bool) – Describes the dimensionality of the field. Currently unused.

• display_name (str) – A name used in the plots

add_output_field(name, sampling_type, **kwargs)

alias(alias_name: tuple[str, str], original_name: tuple[str, str], units: str | None = None, deprecate: tuple[str, str | None] | None = None)

Alias one field to another field.

Parameters:

• alias_name (tuple[str, str]) – The new field name.

• original_name (tuple[str, str]) – The field to be aliased.

• units (str) – A plain text string encoding the unit. Powers must be in python syntax (** instead of ^). If set to “auto” the units will be inferred from the return value of the field function.

• deprecate (tuple[str, str | None] | None) – If this is set, then the tuple contains two string version numbers: the first marking the version when the field was deprecated, and the second marking when the field will be removed.
