The measured dark noise was (21 +- 2) nV/rtHz.
The noise data was fit to with the following results:
V,,d,, = (21 +- 2) nV/rtHz
Z,,RF,, = (77 +- 3) kOhms
chi^2^ / ndf = 0.006		 The noise data was fit to attachment:fitfunc.png with the following results:

Z,,RF,, = (2.07 +- 0.01) kOhms

I,,d,, = (24.7 +- 0.6) mA

chi^2^ / ndf = 42
