class pyphot.ezunits.pint.AliasDict(*args, **kwargs)

Bases: dict

add_alias(key, value, preferred=False)

get_aliased(key)

exception pyphot.ezunits.pint.DimensionalityError(units1, units2, dim1=None, dim2=None)

Bases: ValueError

Raised when trying to convert between incompatible units.

exception pyphot.ezunits.pint.UndefinedUnitError(unit_names)

Bases: ValueError

Raised when the units are not defined in the unit registry.

class pyphot.ezunits.pint.UnitRegistry(filename='', force_ndarray=False)

Bases: object

The unit registry stores the definitions and relationships between units.

Parameters

• filename – path of the units definition file to load. Empty to load the default definition file. None to leave the UnitRegistry empty.

• force_ndarray – convert any input, scalar or not to a numpy.ndarray.

add_from_file(filename)

Add units and prefixes defined in a definition text file.

add_prefix(name, value, aliases=())

Add prefix to the registry.

add_unit(name, value, aliases=(), **modifiers)

Add unit to the registry.

get_alias(name)

Return the preferred alias for a unit

class pyphot.ezunits.pint.UnitsContainer(*args, **kwargs)

Bases: dict

The UnitsContainer stores the product of units and their respective exponent and implements the corresponding operations

add(key, value)

pyphot.ezunits.pint.converter_from_reference(scale, offset, log_base)

pyphot.ezunits.pint.converter_to_reference(scale, offset, log_base)
