cwitools.synthesis.sum_spec_r

cwitools.synthesis.sum_spec_r(fits_in, ra, dec, redshift, radius, var_cube=None, wmask=None, rescale_cov=False)

Get summed spectrum of a region specified by a center and radius.

Parameters:

• fits_in (HDUList or HDU) – The input FITS with data cube
• ra (float) – The right-ascension of the central position, in degress.
• dec (float) – The declination of the central position, in degrees.
• redshift (float) – The redshift of the source
• radius (float) – The radius, in proper kpc, within which to sum.
• wmask (list) – List of wavelength tuples to mask

Returns:

Table with columns ‘wav’ (wavelength), ‘flux’,

and - if var_cube was provided - ‘flux_err’.

Return type:

astropy.io.fits.TableHDU
