eff_from_geom_area

pycraf.conversions.eff_from_geom_area(geom_area, eta_a)

Effective antenna area from geometric area, given antenna efficiency.

The effective and geometric antenna areas are linked via the antenna efficiency:

A_eff = eta_a * A_geom.

Parameters:

geom_areaQuantity

Geometric antenna area, A_geom [m**2]

eta_aQuantity

Antenna efficiency [%, dimless]

Returns:

eff_areaQuantity

Effective antenna area, A_eff [m**2]

Notes

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