Why don't the interference plots of the delayed-choice quantum eraser go to zero?

In the original paper on the delayed-choice quantum eraser by Kim et al. [Phys. Rev. Lett. 84, 1 (2000)], the plots of the joint detection rates shown in Figures 3 & 4 do not go to zero. Not even close. I've always wondered about that. The authors don't address it, and I haven't seen any explanation of it elsewhere. In the classic double-slit experiment, intensities go to zero (or close to it) at the nodes of the interference pattern.

Let me just say that I believe I have a fairly simple explanation for why the plots don't go to zero, but I hesitate to share it here because the links to my two papers on this are located on my website. I don't want to trigger some arbitrary spam filter or violate any rules of this forum.

However, I have found that my attempts to answer this key question gave me much more insight into the workings of the experiment. I would love to hear your thoughts on this and share mine, if you're interested...
