When the Op On button (second button from the left on the top strip of an SIRS+DTV RAMP, as depicted in Fig. 2, is selected the window depicted here opens (panel A.). At the bottom left hand side we see that we have four RAMs (runtime alterable modules) options pertaining to the formulations of the functions Kappa (κ(t)), rIT (ρIT), rSV (ρSV) and rRV (ρRV). We also see that the Kappa RAM has been selected. The Default option (number 0) of this RAM is the adaptive form given by Eq. 10 (it appears in the window on the left of panel A., with some specific details pertaining to this mode provided in the window on the right of panel A.). Inset B. shows the alternate form (number 1) for κ(t), which is simply setting it equal to the constant κ0. The user may insert an additional alternate form for this RAM by selecting the ‘plus’ button, bottom middle of panel B., and then adding the desired from in the Code window on the left-hand side
