How to use Aladin Lite user interactively?


I am Celine Mang, a junior at Vanderbilt University. I have enjoyed exploring the website( )and was truly inspired. I am currently building a similar website using Aladin Lite, aimed at displaying user-uploaded files, and find myself in need of some expert advice.

Could you kindly share which components of the Aladin Lite open-source code were utilized in the creation of this site?

I am also curious whether the website was constructed exclusively with HTML, CSS, and JavaScript.

Lastly, I would appreciate any insights into how user-uploaded files are integrated into the Aladin Lite map.

Your expertise and any guidance you could provide would be invaluable to me as I undertake this project independently.

Thank you very much in advance.

Hi @celinemang, just a quick note to say thanks for this question, and that I’ve moved this topic into the “Support - Lasair” category as it seems best suited for a Lasair developer to answer (perhaps @roy?).

Oh, okay! Thank you so much!

Hi Celine
First to say Aladinlite has excellent documentation and example code. I think it would be difficult to disentangle the Lasair code, so I direct you there.

The Lasair front page and object page: Each of these is based on adding markers to AladinLite as in this example code.

Lasair’s Gravitational Wave skymap, is based on adding markers as above, but also displaying a MOC file as in this example code.

Hope this helps. If you have more specific questions you could contact me directly at or the builders of AladinLite at


Hello Roy,

Thank you so much for your answer. It really helped me a lot!
Also, I asked you another question via your email. Thank you!
