A8.3 USER-DEFINED MODE

In this case, the receiver attenuation is a direct input with positive values in dB. Therefore SEAMCAT will take the receiver attenuation a_VLR(Df) values directly from the function (might be also constant value) that you entered.

a_VLR() = block_{Use defined} () (dB)                                       (Eq. 123)

where  = (f_ILT - f_VLR)
