Subtraction of dark noise from locking accuracy measurement

I subtracted the dark noise from the locking accuracy measurement done in elog2864. I calculated sqrt(locking accuracy^2-dark noise^2). In the point where the dark noise is larger than the locking accuracy, the subtraction is set to 0. The rms after the subtraction is almost the same as one before subtraction.
