Hi folks,

SIA service down? Bug?

Code fragment and error message below.I tried a few other surveys as well, so I'm guessing I've got the wrong syntax or the service is down/broken. Good hunting!



### Code Fragment

DEF_ACCESS_URL = "https://datalab.noao.edu/sia/stripe82_nsa"
svc_stripe82 = sia.SIAService(DEF_ACCESS_URL)

ra = 335.0 # in degrees
dec = 0.0 # in degrees
fov = 0.1 # in degrees

imgTable = svc_stripe82.search((ra,dec), (fov/np.cos(dec*np.pi/180), fov), verbosity=2).to_table()

### Error Log

Hi Dave,

I had to bounce the service to clear an out-of-memory error, please try again and let us know if the problem continues.

Cheers, -Mike

I just tested Dave's snippet and it worked. Came here to find Mike was already on it :)
BTW, thanks Dave for one of the clearest issue reports ever seen here!
Thanks Mike, thanks Robert. Confirmed it works on my side. Be well - dave
