I am trying to access DeMCELS DR1 images for my research, but I am unable to access them through either the SIA service or the Astro Data Archive.

Question

1. The DeMCELS SIA endpoint
   https://datalab.noirlab.edu/sia/demcels_dr1
   returns HTTP 404 – Not Found. Using pyvo results in a DALServiceError because the endpoint returns an HTML 404 page instead of a VOTable.
2. The Astro Data Archive search portal
   https://astroarchive.noirlab.edu/portal/search
   returns HTTP 500 – Internal Server Error in my browser.

Are these services currently unavailable, or have the DeMCELS SIA endpoint or archive URLs changed? If these are known issues, is there an alternative way to access the DeMCELS DR1 FITS images?

Answer 1

Thank you for reaching out. Please try again, we have fixed some erroneous config on our end. The demcels_dr1 endpoint is working.

The Astro Data Archive SIA services native to the archive is actually:
https://astroarchive.noirlab.edu/api/sia/voimg

Your endpoint is to the (interactive) portal. Note that the Archive's SIA service acts a bit differently from the Data Lab one.

We hope this is helpful, and thanks again.
