That sounds like IRAF. I recall trying to fit a high order polynomial to a dataset and IRAF crashed inelegantly. I had asked for a higher order than the data would permit but, rather than tell me so, it just died instead. Its very powerful, but assumes that those using it don’t do things that are daft.

Its worth learning…

Cannot say whether there was a GUI. You would think so after all these years but professional astronomers are perfectly happy with personalised batch files processing chains akin to a DOS .bat file. Its us Windows users who have gone soft 🙂
