During the daily run call today, Adam Mullavey mentioned that the hardware injection team is planning to do a series of coherent hardware injections over the weekend.  The software which selects event candidates and generates EM alerts, "Approval Processor", had been configured to treat hardware injections like real triggers, but that would've caused problems for the hardware injection tests.  So this evening (at 21:00 PST) I have changed the configuration of Approval Processor to make it ignore hardware injections.

This configuration change has been documented in the Bursts/EMFollow wiki at https://wiki.ligo.org/Bursts/EMFollow/SoftwareRecord .
