The floor of the sensitivity curve for the gps=1230861618,  was generated using the following parameters:

aLF=2.0e-22;
aMF=7.78e-24;
aHF=2.86e-24;
POLE=abs((1i*f+56)/56);
LFN=aLF./(f/20).^4;
MFN=aMF.*(f/100).^0.25;
HFN=aHF*POLE;
THLFN=3.8e-22./(f/10).^2.5;
THMFN=1e-23./(f/40).^.5;
THERM=(THLFN.^2+THMFN.^2).^.5;
DESIGN=(THERM.^2+HFN.^2).^.5;

TOTAL=(LFN.^2+MFN.^2+DESIGN.^2).^.5;

This was used to compare and calculate the gain/loss of Mpcs in BNS range for several peaks.
