TypeError – if name, unit and end are not of type str

class pixSED.misc.misc.PhysicalLogQuantity(value: Any, *args, unit: str = '', **kwargs)[source]#

Bases: object

Code author: Wilfried Mercier - IRAP/LAM <wilfried.mercier@lam.fr>

Implement an Astropy Quantity which can have log of physical values.

Arguments

__str__(*args, **kwargs) → str[source]#

Code author: Wilfried Mercier - IRAP/LAM <wilfried.mercier@lam.fr>

Slightly modified string representation.

toPhysical(*args, **kwargs) → Quantity[source]#

Code author: Wilfried Mercier - IRAP/LAM <wilfried.mercier@lam.fr>
