Ce que tu as fait va exactement dans le sens de ce qu'il faut faire en spectroscopie echelle car on constate que les optiques pho...

Hello Robin,

Thanks for the paper.
This is very interesting and shows that there are investigations to be done on this star

Your remote installation is very good and the Voyager software seems to be a good solution to control everything remotely and automatically.

Hi Robin, Yes you are right, it is because we are in Chile under an exceptional sky that we can free ourselves from an IR for each target. The nights are very stable and very repeatable from one night to the next except for a few rare nights where we have clouds or a bit of fog. In automatic mode, w...

Hello Pete, we manually made "generic" instrumental responses at various heights in the sky (every 10 degrees, from 30 degrees to zenith), in fact a library of IR Afterwards, when making automatic observations, a target list is created in a .csv format with the name of the target, its coor...
