Data Lab Cutout Server Issue

Question

trying to download images for

ra     dec
158.991625 58.979488

from the cutout server at https://datalab.noao.edu/sia.php I get the following info,

which is weird not only because the thumbnail icon shows up as a question mark

(and I get an error if I click on the question mark) or because exptime shows up

as zero but also because I select all images try and click on 'download fits' nothing seems to happen.

Any thoughts? Thanks!

Hi Mattia,

Thanks for the question!  So there appears to be some bad information in the Legacy Survey DR6 image metadata table, that we will need to fix.  In the meantime, you can get access to the image from which the cutout is made by right clicking on the image thumbnail link, copying the link into your browser, and editing the "extn=2" argument to "extn=0".  Apologies for the hackaround, we will examine the table and repair the bad information.

Cheers, Knut
