I was trying to follow step by step like we did at the workshop, take a spectrum of a target star and use a similar class of star in the ISIS library for the response. Must admit I do get confused when to take a reference star`s spectrum and when a library one.
I do remember now to use an A or B type for response, my bad !!. Those spectra above are simply the result of using an A9III Miles library star for the response which is obviously incorrect, Think that RMS got the better of me 😉
thanks for that!
