* Due to having only two projections (order_0 & 1 images), the deconvolution is not good enough to reveal small or changed-rapidly structures. But considering 1" scanning usually takes long time to finish (in this case, 80 minutes for a small FOV), it is also not good enough to observe fast-changing features. So it looks the slot deconvolution would be useful for, for example, synoptic velocity review(?)
