effects.core

This module defines the Effect class to construct sncosmo effects with associated parameter models.

class skysurvey.effects.core.Effect(effect=None, name=None, frame=None, model={})

Bases: object

A class to represent effects (e.g. dust, scatter) to be applied to a transient template.

Parameters:

• effect (sncosmo.PropagationEffect) – Propagation effect.

• name (str) – Name of the effect.

• frame (str) – ‘rest’: rest-frame ‘obs’: observator-frame

• model (dict) – model parameters.

classmethod from_sncosmo(effect, name, frame, model={})

Load an effect from a sncosmo effect.

Parameters:

• effect (sncosmo.PropagationEffect) – Propagation effect.

• name (str) – Name of the effect.

• frame (str) – ‘rest’: rest-frame ‘obs’: observator-frame

• model (dict) – model parameters.

Return type:

Effect

classmethod from_name(name, which=None)

Load an effect from its name.

Parameters:

• name (str) – Name of the effect. Could be: mw, hostdust, scatter.

• which (str) –

  which model to use for the effect.

  • for mw: ccm89 (default)

  • for hostdust: ccm89 (default)

  • for scatter: g10, c11

Return type:

Effect

property effect

Access the effect.

property name

The name of the effect.

property frame
