Class ContinuumDivision

Initializing a ContinuumDivision instance.

Parameters:

• star_grid (list[Star()]) - The parameter sets for which the fitting is done

  (default: [])

• spec (list[Sed()]) - information concerning dust data available for star

  (default: [])

• franges (list[float] or list[list[float]]) - The fitting ranges for this instance. 4 values in mic, delimiting 2 parts of the spectrum blueward and redward of the dust feature. Default is for 3.1 micron ice feature. Can also give a list of lists, in which case the franges are defined for every Star() and Sed() included, such that len(franges) == len(spec)+len(star_grid). The model franges are listed first, then the sed franges. Can also be given through the cfg file, and takes priority in that case.

  (default: [2.6,2.85,3.3,3.7])

• plot (bool) - Show the continuum division and fitting plots.

  (default: 0)

• func (string or list[string]) - The function used for fitting the continuum. Can be a list of functions as well, of len == len(star_grid) + len(spec) Can also be given through the cfg file, and takes priority in that case.

  (default: power)

• cfg (string) - a configuration file for Plotting2.py.

Overrides: object.__init__

Calculate the equivalent width after continuum division.

Parameters:

• dtype (string) - data type (only 'model','sws' for now)
• frindex (int) - The index in the franges list for this entry.

Prepare models for dust feature continuum division.

The equivalent width of the feature is also calculated here.

Prepare data for dust feature continuum division.

For now only SWS is available.

The equivalent width of the feature is also calculated here.

Divide flux by the continuum flux in a dust feature.

Parameters:

• w (list/array) - The wavelength grid
• f (list/array) - The flux grid
• dtype (string) - data type (only 'model','sws' for now)
• frindex (int) - The index in the franges list for this entry.
• plot (bool) - Show a plot of the continuum division
