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
