Match Object

This module defines the Match class that is used in fitting routines.

class smsyn.match.Match(*args, **kwargs)

masked_nresid(params, **kwargs)

Masked normalized residuals

Return the normalized residuals with masked wavelengths excluded

Args:

params (lmfit.Parameters): see params in self.model

Returns:

array: normalized residuals where self.wavmask == 1

model(params, wav=None, **kwargs)

Calculate model

Return the model for a given set of parameters

Args:

params (lmfit.Parameters): Parameters object containing at least

teff, logg, fe, vsini, psf, and spline coefficients

wav (array): (optional) array of wavelengths at which to

calculate the model. Useful for generating a more finely sampled model for plotting

**kwargs: extra keyword arguments passed to lib.synth

nresid(params, **kwargs)

Normalized residuals

Args:

params (lmfit.Parameters): see params in self.model

Returns:

array: model minus data divided by errors

resid(params, **kwargs)

Residuals

Return the residuals

Args:

params (lmfit.Parameters): see params in self.model

Returns:

array: model minus data

spline(params, wav)

Continuum model

Unpacks the params object and returns a spline evaluated at specified wavelengths.

Args:

params (lmfit.Parameters): See params in self.model wav: array of wavelengths at which to calculate the continuum model.

Returns:

array: spline
