In Part I, we saw how selection of the left-right integration limits affects the computed and reported results of a peak with a known value.
Having looked at left and right, let's look at up and down.
Up is defined by the top of the peaks in question, so there is nothing to be done there. But down at the bottom, unlike the clean theoretical examples in Part I, there is in reality background noise, and we need to decide what to do about it.
Therefore, we see clearly that decisions made for background subtraction have significant effects on the computed results, and that sloping backgrounds complicate matters making the background subtraction more difficult to select.
These complications are true in the simplest, clearest possible examples with peaks having known values.
In Part III, we'll look at the confusing effects of neighboring peaks.
