Hi Joan,
Wow, this is an amazing piece of work you’ve done! Truly impressive!

Cheers

Re: GK Per Outburst

Hi Christophe,
I don't have much time available and the weather is really bad right now :cry:
However, I will try to do some more GK Per spectra in February !
And yes, I sent my spectra to the aras database :D

Clear skies

Top ce spectre Hubert ! Merci pour le partage.
J'espère aussi pouvoir la tenter prochainement, quand la météo sera un peu moins capricieuse ;)
Pour le guidage c'est quoi le soft en question ?
