No, sorry. I usually do not keep files around that long. Here’s another one to download:
This is an actual capture of a black rollout section. Enhancing the red channel, you see the horizontal noise stripes:
Again, I want to argue against the light source being the cause of these horizontal stripes. As already mentioned, they should not be present with a cap over the lens.
Capture your empty film gate (without any film) so that the gate appears medium gray. That is, you do not want any part of your gate to burn out. Note that this requires a shorter exposure than the one you are using when capturing film. If intensity modulations are present in your illumination, you will see them once you increase your contrast level. That is also a good technique to check whether your illumination is even or shows some vignetting. And to check whether your sensor/lens is dirty of dust. I bet you are not going to see any horizontal stripes.
At this point in time, I am tending slightly toward the assumption that maybe the stripes are caused by stray illumination from your room lights through the camera’s PCB. Can you run your lens-cap-on test with all lights in the room switched off? It’s just a shot in the dark, trying to find a black cat in a coal cellar…
