Class Spire

Initializing an instance of Spire().

Parameters:

• star_name (string) - Name of the star from Star.dat
• resolution (float) - The spectral resolution of the SPIRE apodized spectra
• oversampling (int) - The SPIRE instrumental oversampling, for correct convolution of the Sphinx output. This is the oversampling factor for the apodized spectra!
• path (string) - Output folder in the code's home folder

  (default: 'codeSep2010')

• intrinsic (bool) - Use the intrinsic Sphinx line profiles for convolving with the spectral resolution? Otherwise the beam convolved line profiles are used.

  (default: 1)

• path_linefit (string) - The folder name for linefit results from Hipe (created by Maries script, assuming her syntax). The folder is located in $path_pacs$/$star_name$/. If no folder is given, no linefits are processed.

  (default: '')

Overrides: object.__init__

Prepare Sphinx SPIRE models by checking if the convolved spectrum is already present in the Spire object and if not calling convolveSphinx.

Parameters:

• star_grid (list[Star()]) - list of Star() instances
• redo_sphinx_prep (bool) - redo the sphinx prep, regardless of whether this Spire instance already did it once, for instance in case the star_grid changed

  (default: 0)

Return the sphinx convolution and return if it has already been done.

Returns None if the convolution is not available.

Parameters:

• star (Star()) - The Star() object
• fn (str) - The filename of the dataset (band) for which the convolution is to be returned.

Returns: array

The sphinx convolution result. (wavelength,flux)

Read the data from the line fit procedure done with Maries Hipe script.

Assumes structure and syntax as given in the example file /home/robinl/Data/SPIRE/rdor/lineFit/lineFitResults

The line fit results are saved in self.linefit as a np.recarray.

The relative FWHM is given with respect to the intrinsic SPIRE resolution for unapodized spectra, i.e. 0.04 cm^-1.

The columns include (with unit indicated): band freq_in (GHz), freq_fit (GHz), wave_fit (micron), line_flux (W/m2), line_flux_err (W/m2), line_flux_rel (ratio), line_peak (W/m2 m), fwhm_fit_freq (GHz), fwhm_fit (micron), fwhm_rel

Parameters:

• kwargs - Extra keywords for the readCols method.

  (default: dict())

Returns: list[array]

The line fit columns are returned.

Overrides: cc.data.instruments.Instrument.Instrument.readLineFit
