Hi Paul,

I am at a loss to know what it is doing. It could perhaps be using the flat lamp as a reference assuming a nominal black body spectrum for the flat lamp including allowance for typical atmospheric extinction, but then why would it need the reference star library spectrum at all, and what is it comparing the library spectrum  against ?  It does seem to work though. I shall have a play, but I am not sure I would ever fully trust it !
