FRS11570

Jeff, Gabriele, Dave

This morning we had another instance of the H1LSC_SRCL1 filter-module giving a very high output when an offset is enabled and FM1 is attempted to be switched ON.

The attached image shows:

1. Input is turned OFF
2. OFFSET is set to 1.0 and is turned ON
3. FM1 has been attempted to be turned ON

The result is that FM1 is not turned ON, but the output of the filter-module goes very high (1.2e+10).

On Monday changes were being made to this filter around the time the problem occurred. Today it appears to have broken spontaneously.

As with Monday, restarting the h1lsc model fixes the problem.

Here is the "+106dB" filter line in the H1LSC.txt filter file:

 LSC_SRCL1 0 12 1   4915      0 +106dB     2.000000000000000000000000e+05   0.0000000000000000   0.0000000000000000   0.0000000000000000   0.0000000000000000
