Components¶

A “Component” in spexxy describes a component in a fit, which in general is a collection of parameters and a method to fetch data for a given set of parameter values. Typically, a component build on top of a Grid or an interpolator.

spexxy comes with a few pre-defined grids:

SpectrumComponent is the base class for all components that serve spectra.
StarComponent contains a single spectrum and adds LOSVD parameters.
GridComponent wraps a grid or an interpolator into a component and adds LOSVD parameters.
TelluricsComponent is just a convenient class derived from GridComponent <spexxy.component.GridComponent> that changes the default’s component name.
