Q1 Euclid Projection Issues
There seems to be an issue with the projection in Euclid Q1 data.
An example can be seen here, where the diffraction spikes of a star show corners/bends. This is still present further down in the next extended galaxy

This is also present in the NIR bands and the "euclidised" ugriz.

Dear Laslo,
Many thanks for the screenshot. We can't repeat the issue with our versions of Edge and Firefox, therefore, the team has created two jsbin pages that should help us figure out if the issue will be resolved by upgrading the aladin-lite version (the tool we use to display the sky).
Using the latest version of aladin-lite: https://jsbin.com/dumibovegu/1/edit?output
Using the current version that ESASky is using: https://jsbin.com/lijobisafo/1/edit?output
Could you open both links and click on "Run with JS" and let us know which of them, if any, shows the same issue that you have in ESASky?
Many thanks and regards,
Deborah
Dear user,
We can't see any bends or corners in the diffraction spikes when we load the same regions in ESASky. Could you try refreshing your window, or try in a different browser, and if the problem still persists, send us a screenshot?
Many thanks!
Deborah, on behalf of the ESASky team
Dear Deborah,
here a screenshot:
Perhaps I did not specify enough, but the artefacts as shown in the screenshot are persistent in Edge and Firefox if I load the website with the given link.If I zoom out enough they vanish.
Kind Regards,
Laslo
