Simulation with pybeams_fits module and periodic pointing error gives the following error for example- sim.py

node 'E:S+0:0': <2 exceptions> (while getting result for request ev.0.0.0.0.10)

and for turbo-sim.py:

node 'ET0:0': <2 exceptions> (while getting result for request ev.0.0.0.0.2)

which repeats until flood control kicks in.

Static pointing error doesn't cause it and neither does the analytic beams module. I've tried it with simulated and EVLA measurement sets and gridded and Tigger sky models. I think it must be a new thing as I've essentially replicated what was done in Portugal to describe the EVLA dE's.

I updated and rebuilt this morning. I've also removed all the print statements from Services.py so I think everything's back to normal.

Cheers.

Hmmm, not sure if this ever worked at all -- there was a real bug which would get triggered when the pointing errors are (at least technically) a function of time. We may have been using static pointing offsets in Portugal, so the bug went unnoticed.

Anyway, fixed in Cattery r8781.
