Missing Gc samples at SC_WE
As reported at Lost samples every 5000 seconds since the new relock after the several restart of GC to reach a correct elapsed time there is many events where the SC_WE DSP uses at least 2 times the same zGc corrections .

The first plost showns the Alp_Det_Horizon and the number of miss functionning event per second: some jumps of the Alp_Det_horizon are due to this misfunctionning.

The second plot is a zoom of one event at GPS870824392. During this second there is burst of events (6 events) and it appears that the same sample is used 2 times by the DSP Sc_WE.
One can noticed that the Gc_WE_z and the Sc_WE_zGc correlation is bad after 100Hz while for the NE everything seems to be correct


All the miss functionning events are available on the file /virgoData/LDMoni/VSR1-LoopDelay.txt file
