Félicitation pour ce papier.

En plus des beaux résultats, il est a souligner la ténacité pour ce projet, car il a duré plusieurs années si je ne me trompe pas. (c'est ce que l'on a vu aux PROAM de Bordeaux l'année dernière).

Vive les amateurs (et les pros!)

Par rapport aux spectres de HD23642, comme sa période est assez rapide 2.5J et sa magnitude de 6.9 , quels sont les temps d'acquisition ?
1200s d'intégration en 3x400s ?

I was all ready to get some high R (Greater than 10K) resolution spectroscopic binary data, but when i clicked the installer
it was a broken link; see: https://www.vub.be/STER/JAD/JAD10/jad10_3/install.msi.

Any other place on the web this SBS: Spectroscopic Binary Solver MS quickbasic program can be downloaded for free?
(I Googled it, but no viable hits......Saw the Austin, TX one, but the description does not match what D.O. Johnson wrote.)
