Thank you, Francois, for the clarification on the Fe II absorption trough differences. Patiently waiting for clear skies here in 'sunny' California. Should night skies ever clear, I intend to record a series of spectra to look for short period variations in the Fe II absorption. A project, it would ...

Hello group

I recently recorded low resolution spectra for V694 Mon [MWC560] and as expected the H Balmer absorption troughs are narrower than in spectra recorded early last year, shortly after the major outburst. I have a basic understanding of how the absorption troughs relate to polar jet ...

V694 Mon low resolution spectrum from 06 April, essentially identical to all my previous V694 spectra.

A couple more low resolution spectra of V694 Mon, 31 Mar and 02 Apr UT. The spectra are essentially identical both nights.

Hello
This is my first time posting to the forum....so go easy on me. I've had 3 opportunities to collect V694 Mon low resolution spectra. Comparing the results from 3 nights, particularly at 4861 was suggestive, but considering the resolution, hardly quantitative. Still, suggestive.

Jim,

I wrote a basic beginners guide last year for students here at UWA. It's in English and although just the basics, includes IR correction and some extra bits at the end. It can be downloaded here:

Thank you, Peter, I will make changes to file name as you suggest.

Indeed, Vincent and Jacques, I have not indicated the working directly as noted. Many thanks.

There is quite a bit of documentation to go through and absorb. Hopefully, I won't be too big a pest to the group while climbing up the ...

Finally sat down to start learning the ISIS program using the Alpy 600 tutorial and immediately hit a wall. I'm using an Atik 420M camera and Artemis image capture software. I tried loading a raw FIT image -- HD15558_003.fit. Got this error message: ERREUR : le chemin du repertoire de travail n'est ...
