Unfortunately, if you leave out the focal length parameter as I did, 
Plop sometimes gets confused.  (I could have sworn it worked for me before!)  
I've updated the files below so that they have all of the parameters needed, 
which Plop will override for you as you enter values in the auto cell mode.

The rest is as before.

Also updated.
