I tried to return to a notebook that I had that finds objects in ls_dr7. When I perform an svc.search, it tries to do it for a few minutes but will return with a chain of errors, all of them being something along the lines of Timeout Error, Max Retry Error, Connection Error. This exact same code worked about 2 months ago. I tried this in both jupyterlab and the classic jupyter interface.
Here is what you need to run it:
DEF_ACCESS_URL = "http://datalab.noao.edu/sia/ls_dr7"
# DES SIA service URL
svc = sia.SIAService(DEF_ACCESS_URL)
ra,dec = 356.12546,0.320592
imgTable = svc.search((ra,dec),(fov,fov), verbosity=2).to_table()
