Sensor correction tests on ITMY

I'm running a sensor correction test on ITMY, using some swarm designed filters from SamC at Birmingham. This is currently engaged in a SEI_CONF state called TEST_SWARM, which is state number 101. Given the state of the BRSes (BRSX was driven out of range at the beginning of Oct, BRSY is getting close), we should not use any states that rely on these sensors, so if it looks like it is necessary to revert my sensor correction test SEI_CONF should be switched to either VERY_WINDY or SC_OFF. If there are any questions about getting back to a normal state, my phone number or email is probably around somewhere.

Attached bode plot shows the new filter in blue compared to the nominal filter in red.
