Class Sed

Initializing an Sed instance.

Setting starting parameters from a star object.

Parameters:

• star_name (string) - The star name of the object
• remove (list[str]) - Photometry to be removed from the output file. e.g. ['WISE','DENIS']

  (default: [])

Overrides: object.__init__

Select available data.

Based on the data file types in Sed.dat and the available data files.

Also calls the buildPhotometry method to create a photometry file from the IvS Sed builder tool

Any keywords required for buildPhotometry can be passed here.

Read the photometry band information associated with photometry of this SED.

Parameters:

• level (float) - The level at which the cut off for significant transmission of the photometric bands is placed.

  (default: 0.5)

Helper method to retrieve the Ak extinction magnitude for a given distance.

The Ak values are saved in the sed object, to cut down the overhead in subsequent calls.

The law and map have to be passed as well. Defaults are marshall and Fitz2004Chiar2006 respectively.

Parameters:

• distance (float) - The distance to the source. If the default, the total extinction is calculated in given direction.

  (default: None)

• map (str) - The galactic 3d extinction model.

  (default: 'marshall')

• law (str) - The reddening law

  (default: 'Fitz2004Chiar2006')

Returns: float

The extinction magnitude in K-band for the requested distance.
