apply_atran

sofia_redux.instruments.fifi_ls.telluric_correct.apply_atran(hdul, atran, cutoff=0.6, skip_corr=False, unsmoothed=None)[source]

Apply transmission data to data in an HDUList.

Parameters:
hdulfits.HDUList
atrannumpy.ndarray

(2, nwave) where [0, :] = wavelength and [1, :] = transmission

cutofffloat, optional

Used as the fractional transmission below which data will be set to NaN. Set to 0 to keep all data.

skip_corrbool, optional

If set, telluric correction will not be applied, but ATRAN spectra will still be attached to the output file.

unsmoothednumpy.ndarray, optional

Unsmoothed transmission to attach to output file. (2, nwave) where [0, :] = wavelength and [1, :] = transmission

Returns:
fits.HDUList
