I've started learning MIDAS as I'm on Linux. In my research into the pro's and cons of MIDAS over Iraf, I see that the Iraf website now recommends Astropy.
It would seem to be the way forward in professional data reduction also and a couple of packages are available for spectroscopy.
Has anyone tried the python way?

Re: Astropy Data Reduction
Hello Stu,
I have analyzed meteor spectra with different software for a while. Since this requires quite specific processing and I could find nothing suitable, i developed my own program. I used Python, also astropy, because it contains many of the required tools, eg. for reading images, transforming them, plotting and least square fits.
To get an idea of what I did, you may look at https://meteorspectroscopy.org/, in particular at
https://meteorspectroscopy.org/2020/03/ ... w-version/
If you are interested in it, please give me a short mail
Regards,
Martin

Re: Astropy Data Reduction
Hello Martin,
Congratulations on programming your reduction code, it looks great and I am very much interested so will email you.
It seems Python is the way forward so will need to up my knowledge and learn.
I wondered if the existing pyDIS would be an option and if you see any pitfalls?

Re: Astropy Data Reduction
Hi Stu,
If you are looking for a spectral processing and analysis software to manage our spectra on Linux, there is Spcaudace: http://spcaudace.free.fr.
It a plugin of Audela free software in English and French language that can be ran on Linux/Win/MacOS systems. There is an ubuntu package available (http://spcaudace.free.fr/installation.php).
A documentation for runing pipelines and astrophysics analysis is available at http://spcaudace.free.fr/docs/index.php ... ccueil.php. A Google translate is fine.
Cheers,
Benji

Spcaudace spectroscopy software: saving you hundred hours of frustration.
Re: Astropy Data Reduction
Thanks Benji,
Your excellent Spcaudace software was on my "to do "list for downloading so thanks for the timely reminder.
Thank you for making a Linux version too!
Cheerio,
Stu
