Here is my time lapse of 9 observations of pi aqr h alpha profile Atik 460 mono C14 Lhires III 2400 l/mm grating
from 02-08-2019 to 10-01-2020.

I think this is an effective way of showing changes in spectral profiles over time.

Many thanks to John Paraskeva creator of BASS for his help in creating this animation.

Enjoy,

Hi, Jack,

for quantitative measurements you should clean the spectra from the water lines of the atmosphere otherwise the emission is too much disturbed. How did you rectify the spectra? Note that electron scattering dominates the line wings which makes them quite broad.

For an intuitive presentation such movies are very nice. But only for that.

Greetings, Thomas

BTW: I checked the translation and see that you use Google Translator. A much better result is delivered by DeepL https://www.deepl.com.

Thomas,

Thanks for your comments.

How did I rectify the spectra ? I don't understand your question please explain in plain English.

Thanks for the link to deepl.com.

Vielen Dank für Ihre Kommentare.

Wie habe ich die Spektren korrigiert ? Ich verstehe Ihre Frage nicht, bitte erklären Sie sie in einfachem Englisch.

Vielen Dank für den Link zu deepl.com.

Jack,
again my comments to your time lapse demonstration:
our current Halpha monitoring of pi Aqr shows a more or less balanced matter and density distribution within the disk of the primary star. That means we do not have to expect at present an appreciable variabilty of the Halpha V/R ratio. We have to wait and see when this process of profile variations starts again. Since you are member of our long-term monitoring you will informed in time when this process will be cognizable.
Nevertheless your time lapse demonstration seems to be a nice possibility to show such a kind of Halpha profile variability.

Best wishes, Ernst

Ernst,

Thank you once again for your feedback.

Time lapse animations could be very useful for future monitoring.

Please keep me informed of developments.
