I took 45 measurements (if the rock was not in the way) on each plane.
I actually started with this grid on the front of the tank. Every 6 inches top to bottom left to right. I may try to somehow overlay the graphs onto this image to make a 3D representation but it doesn't really make much difference since I have a pretty good idea what Im getting for PAR numbers and where..
And yes, in the bottom of the pic my Mandarin is nearly as big as my Tennenti Tang :silly:

I just put all of the measurements into excel in a grid (with labels) exactly as they were laid out while measuring so I had nine by five cells worth of measurements and then created a surface graph with the subtype of contour, formatted the legend to deal in 50's instead of 200's and it was happy.
I can email you the xls file, or bring it by on a flash drive when I bring the apogee back.
