Yeah, so Fitz liberators is an essential tool for the process of turning the data that we get from the digital cameras we have on our telescopes to the color composite images that we make. Maybe the best way to think about it is that a um a grayscale image can only show um 8 bits of data or 256 shades of gray. Whereas the data files that we get from our telescope have a much wider dynamic range. And so what we need to do is we need to convert the high dynamic range data files we have into image formats that can be loaded into Photoshop. The Fitz format is actually used for much more than just images. It's used for different kinds of data like spectroscopy and data cubes and is used on not only optical and infrared telescopes like we have a noir lab but also for radio telescopes, x-ray telescopes and so on. So it's used for a lot more than just making images.
