Hi

Steve,

You're doing well with the ALPY....

The line at around 4690...could be HeII at 4686 ????

Ta Ken!, I still haven`t sussed out the instrument response side of ISIS yet especially Wolf Rayet type stars as there are no reference spectra to divide/compare with and  I`m a bit unsure how to save an instrument response curve calculated from other types.

cheers

Steve, you're doing well.....

According to Simbad AG Dra is a K3IIIep star

If you really wanted to do an IR then a K3 star a similar altitude would be a starting point....

(WR stars are generally classified as O type (e))

Onwards and upwards....

Thanks again Ken, so division by an O(e) type star should be OK for all WR types ?

As a compromise, yes an O type star would work.
