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 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) µm bands, and can be accessed in HIPE after a calibration context has been loaded (see above).
- The observed beams at much finer scale of 1 arcsec/pixel, as well as the theoretical ones, are available from here . Please read the release note for more details.
