EDIT: socs image tag: v0.5.1-22-g7d2f158-dev

Start at socs/agents/ucsc_radiometer/agent.py:83, where the traceback enters the acquisition path, and inspect the response being passed through requests JSON decoding. Reproduce the failure using the reported Radiometer status and socs image tag v0.5.1-22-g7d2f158-dev. Done means the cause of the invalid JSON response is identified and the acquisition no longer crashes on this condition.
