fit_gas_lines

sitelle.fit.fit_gas_lines(z_dim, inputparams, params, lines, V_range, snr_guess=None, silent=False)

This function fit lines in a given spectrum. DEPRECATED It has been deisgned to be parallelized, hence the apparent complexity.

Parameters:

• z_dim (2D ndarray) – z_dim[0] contains the spectrum to fit, z_dim[1] contains theta , the incident angle at which the spectrum was recorded
• inputparams (orb.fit.InputParams) – Output from orcs.core._prepare_input_params
• params (dict) – Parameters of the cube, obtained with orcs.HDFCube.params.convert.
• lines (list of str) – Names of the lines to fit (as defined here)
• V_range (1D ndarray) – The range of velocity to test.s
• snr_guess (float) – Signal to Noise ratio guess (Default = None)

Returns:

A cube containing at each cell a dict with : - ‘line_spectra’: the fitted line spectra - ‘fit_params’: the fitetd parameters of the lines - ‘chi2’: chi2 list, each element corresponds to a velocity in V_range

Return type:

3D ndarray
