In this case, the receiver attenuation is a direct input with positive values in dB. Therefore SEAMCAT will take the receiver attenuation
aVLR(
Df) values directly from the function (might be also constant value) that you entered.
aVLR(Df) = blockUse defined (Df) (dB) (Eq. 123)
where Df = (fILT - fVLR)
