About reference star, it's clear that we nead a brighter star than those proposed by Darryl Sergisson. Darryl agree.
We have to take more spectra from several observers in order to build a common protocol, noticely reference(s) star(s)
For my last acquisition, I used HR1490, a AV2, mag V 5.2
I have some difference in tne continuum shape with Christian's ones.
More spectra are needed to fix the protocol (throught a discission bretween the different obversers) and propose it to Derryl Sergisson
Waiting for your spectra,
