t_a_from_powerflux_nu

pycraf.conversions.t_a_from_powerflux_nu(powerflux_nu, eff_area)[source] [edit on github]

Antenna temperature from spectral power flux density, given effective antenna area.

The spectral power flux density is the power flux density per unit frequency, i.e., powerflux_nu = powerflux / bandwidth.

Parameters
powerflux_nuQuantity

Spectral power flux density [W/m**2/Hz, dB_W_m2_Hz, Jy]

eff_areaQuantity

Effective antenna area, A_eff [m**2]

Returns
T_AQuantity

Antenna temperature [K]

Notes

Because all parameters/returned values are Astropy Quantities (see Quantity), unit conversion is automatically performed.
