Hello Jaroslav,

Thank you for this great list of targets, I will start making some next week.

Hi Peter, For the wavelength calibration, Demetra is configured by default to be used with the following calibration module: https://www.shelyak.com/produit/pf0037-module-detalonnage-alpy/ I'm not sure that in the calibrex, there is exactly the same lamp. According to the suppliers, the Ar/Ne bulbs ...

but nevertheless, could you be so kind to pass them my posting?

Ernst

Of course, i will send your graph.

Hi Olivier, you write in capter 4.3.1: In short, despite our ability to reproduce fairly well the Hα line profile of P Cygni observed in 2020 using such a less intense wind model, it is beyond the scope of the current paper to state that the intensity of the wind of P Cygni varied in this way durin...

Hi Olivier, would you be so kind to send a copy of the paper? Another question: what about the evaluation of the del Sco spectra at BeSS? Are there further not jet evaluated spectra of other observers? Because of the periastron passage radial velocity of the star as much spectra as possible would b...

Here's a publication about spectroscopy and interferometry taken at the same time. The spectroscopy part was made with my eShel spectrograph to have a very good calibration accuracy on the Balmer's lines. The interferometry part was made with two telescopes of one meter in diameter. https://academic...
