The above list is quoting from JAMSAT Home Page.

Example : Trans.= (U-Up) + (S2-Down) = 2837.025

We made trial of AO-40 "(U-Up) + (S2-Down)" at the
beginning of May 2001, then we observed as follows.

Approximation after the our observation : 

          Trans.= (U-Up) + (S2-Down) = 2836.990

          Up(LSB)     Down(USB)
          435.755 --> 2401.235
          435.690 --> 2401.300
          435.560 --> 2401.430
