IRP=1 Linear function

$k_{rl}$increases linearly from 0 to 1 in the range

RP(1) ≤ Sl ≤ RP(3);

$k_{rg}$increases linearly from 0 to 1 in the range

RP(2) ≤ Sg ≤ RP(4)

Restrictions: RP(3) > RP(1); RP(4) > RP(2).

If RP(5) > 0,

$k_{rn}$ increases linearly from 0 to 1 in the range RP(1) ≤ Sn ≤ RP(3);

If RP(5) > 0 and RP(6) > 0,

$k_{rn}$ increases linearly from 0 to 1 in the range RP(5) ≤ Sn ≤ RP(6);

Restrictions: RP(6) > RP(5).
