backgroundSources
Return to directory of Todd's tools
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.
Usage:
au.backgroundSources(fluxdensity, fieldDiameter=None, fieldXsize=None,
fieldYsize=None, frequency=5):
Inputs:
- fluxdensity: minimum detectable flux density at field center (mJy)
- fieldDiameter or (fieldXsize and fieldYsize): in arcseconds
- frequency: in GHz
Example:
CASA <3>: au.backgroundSources(0.1,fieldXsize=40,fieldYsize=60)
Out[3]: 0.043981990938511843
