Synopsis

SMC extinction: the Prevot et al. 1984 model.

Syntax

smc

Description

The interstellar extinction is calculated using the formula from [1] . This model is intended to be used to modify another model (e.g. by multiplying the two together). It is for use when the independent axis is in Angstrom.

Example

>>> create_model_component("smc", "mdl")
>>> print(mdl)

Create a component of the smc model and display its default parameters. The output is:

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
