Duncan, Dave
I installed Duncan's latest version of cal/common/scripts/ext_alert.py and started running it as user controls on h1fescript0 at 15:36PDT. It has been running for an hour so far with no problems, and correclty reported the FERMI GRB event from 20:09UTC (13:09PDT).
You can view the GRB information in the "Latest astrophysical event alert" section of the CAL_INJ_CONTROL MEDM screen, accessible from the SITEMAP via the corner station CAL pull down, "HWINJ CTRL" option.
