I started making regular observations of NELM and SQM in late March last year when I bought a SQM-L device for myself. Then I started a project about collecting these measurements and comparing NELM vs. SQM. Here’s a preliminary graphical presentation of my results. In this graph, there is SQM plotted vs. NELM. This dataset is a compilation of 31 measurements. I also fitted a trend line in the data, and produced an equation for the line which is like this:
This work will be going on and I will be collecting more data to make more solid basis for making conclusions. I have been using Open office Calc to produce this graph and trend line.
Keep on looking for more posts! I’m not done yet!
