pa_pocc_1s_spectra_v10.fits Format: FITS (Flexible Image Transport System) HDU No data. Extension 1 1024 x 3768 Spectra (s**-1) This extension contains the observed solar spectra, corrected for various instrumental effects, during the Pluto occultation. The spectra are stored as a 1024 x N element array (wavelength x time), and are in units of corrected counts per second per pixel. To obtain transmission spectra, divide these spectra by the solar reference spectra contained in extension 3. Extension 2 1024 x 3768 Uncertainty Spectra (s**-1) This extension contains the statistical uncertainty in the observed, solar spectra contained in the primary data extension. Extension 3 1024 x 3768 Reference Spectra (s**-1) This extension contains the reference unocculted solar spectra for the Pluto occultation. For a detailed description of the data reduction process, please see Young et al., (2017) (https://arxiv.org/abs/1704.01511). Extension 4 1024 x 3768 Reference Uncertainty (s**-1) This extension contains the statistical uncertainty in the reference unocculted solar spectra for the Pluto occultation contained in extension 3. Extension 5 1024 Wavelength (Angstrom) New Horizons Alice Pluto/Charon occultation wavelength vector Extension 6 3768 MET Mission Elapsed Time (s) Extension 7 3768 Tangent Radius (km)
