  • SPIRE Photometer Calibration:
    • Full details of the SPIRE calibration can be found in the SPIRE Observers Manual and in dedicated journal papers (Bendo et al. 2013, North et al. 2013)
    • Point Source Flux Calibration ~ 7%
      • ~ 5% absolute from Neptune model
      • ~2% relative from Neptune photometry
    • Extended emission Calibration ~ 11%
      • additional ~4% due to uncertainty in the measured beam area
    • Additionally repeatability of measured photometry to flux densities >100mJy ~ 2%

  • SPIRE Photometer Calibration:
    Full details of the SPIRE calibration can be found in the SPIRE Observers Manual and in dedicated publications: the calibration scheme is described in Griffin et al. (2013) and the implementation using Neptune as the primary calibration standard, is described in Bendo et al. (2013).
    • Calibration uncertainties, which should be included in addition to the statistical errors of any measurement, are as follows:
      • 4% absolute from Neptune model (this uncertainty is systematic and correlated across the three bands)
      • 1.5% (random) from Neptune photometry
    • Extended emission calibration
      • In addition to the above uncertainties, there is an additional 4% uncertainty due to the current uncertainty in the measured beam area
        <--     * Additionally repeatability of measured photometry to flux densities >100mJy ~ 2% -->
 
  • SPIRE Photometer Beams:
    • These are available in the SPIRE calibration context, at the standard map pixel size of (6,10,14) arcsec/pixel for (250,350,500) m bands, and can be accessed in HIPE after a calibration context has been loaded (see above).
Line: 240 to 241
 
    • These are also available in the SPIRE calibration context (photRsrf) and can be accessed in HIPE after a calibration context has been loaded (See above).

  • Neptune and Uranus models used for the SPIRE photometer flux calibration:
Changed:

<
    • The ESA2 models currently used in the SPIRE calibration are available here.
>
>
    • The ESA2 models of the SPIRE calibration, used up to HIPE v10 and spire_cal_10_1, are available here.
    • NEW The ESA4 models of the SPIRE calibration, used from HIPE v11 and spire_cal_11_0, are available here.
