Computes the expected number of background radio point sources above a specified flux density in a specified field size, based on the formula in the Appendix of Anglada et al. 1998.


au.backgroundSources(fluxdensity, fieldDiameter=None, fieldXsize=None,
                      fieldYsize=None, frequency=5):
  • fluxdensity: minimum detectable flux density at field center (mJy)
  • fieldDiameter or (fieldXsize and fieldYsize): in arcseconds
  • frequency: in GHz


CASA <3>: au.backgroundSources(0.1,fieldXsize=40,fieldYsize=60)
  Out[3]: 0.043981990938511843
