Above is the usable map for the space. You should save this full size version (1024x768 pixels) and use as a background spatial reference image in Blender and/or After Effects. I repeat, USE THIS ABOVE MAP as the sole reference for building your scenes.
This may be more for a reference, but above is what the exact rectangle of projected light looks like hitting the space. Probably best not to use this as a map, but interesting to see.
And above is the color map projected onto the physical space. This may help you see what faces have been colored.
In case you aren't able to get the full scale images at 1024x768, here they are ZIPPED up:
