Which expression suits best when the solid angle obtained by the noise source is less than antenna solid angle?

P A B =P B A and T A = ( frac{ Omega_B}{ Omega_A} T_B )

PA A=PB B and TA= ( frac{ Omega_B}{ Omega_A} T_B )

PA B=PB A and TA= ( frac{ Omega_B}{ Omega_A} T_B )

TA= ( frac{ Omega_A}{ Omega_B} T_B ) and PA B=PB A

TA= ( frac{ Omega_A}{ Omega_B} T_B ) and PA A=PB B
