planetFlux {astroFns}

Flux density from a thermal disk

Description

The flux density from a disk-shaped blackbody with uniform temperature observed in a Gaussian beam.

Usage

planetFlux(T = 195, dp = 14.8, thetab = 19.4, f = 32)

Arguments

T

Disk's physical temperature

dp

Planet diameter, arcsec

thetab

Beam FWHM, arcsec

f

Observing frequency, GHz

Details

Geometry is for a uniform-temperature disk, a planet to some approximation, in a Gaussian beam.

Value

Flux density in janskys
