Calculating Signal to Noise Question

Hello Everyone,


I have another question for the Agilent community and I really appreciate the help that this community has given to me. Hopefully I can contribute soon myself. 


I'm trying to calculate the signal to noise ratio for a small peak in my standard run using ASTM set in my processing method. Note, I currently use Open Lab CDS 2.3. 


However, when I look at my signal to noise value in my report it is blank. I've attached an image of the peak I'm trying to calculate signal to noise for down below:



Is the peak too small or should I use a different noise calculation?


Lastly for the noise range, I'm trying to use the noise range of my current run. For the time ranges, is that the time range in the sample run or is that around the peaks of interest? I just needed some clarification on that.



Thanks again for all the help.
