Hi Robin,

Hi Robin,

Yes, as far as I can tell the algorithm uses only a master flat and a database reference to create a ‘synthentic’ instrument response profile, which is why I’m at a loss to explain why the results (including those of several cooler stars that I haven’t published) are as good as they are, given that there is presumably no atmospheric correction applied.

The automated smoothing becomes less reliable beyond type-B and type-A stars which may also limit its use. Despite that, it does appear to be yet another cool little feature in ISIS.
