We use bacteria with [http://partsregistry.org/Part:BBa_I763004 I763004] plasmid, since we know all of them beam fluorescence also when not inducted; we check that the OD value is 1.2. We then execute two different observations:

• ten different spots within the same slide (test A);
• five slides, and two spots each (10 total spots, test B).

For every spot, we take a picture and we elaborate it using the algorithm above, obtaining as output a normalized intensity value. Finally, for each of the two sets of values, we calculate mean and standard deviation; for the B test, we calculate both values either on the 10 intensities indistinctly (B1) and on the five slide means (B2). Here are the results:

	Results
A B1 B2	97.6 ± 17.6 96.1 ± 18.8 96.1 ± 19.1

Complete data set is below.

As we expected, the two mean values are close to each other, being the different spots from the same solution.
