4 Hz glitch

Glitchy error signal of PRCL, SRCL, and MICH.

First screenshot shows the current error signals having glitches, and the second is about 2 hour ago which does not have a glitch, when the PRMI is locked. This glitch appear when I tried to lock the DRMI and due to this glitch the DRMI stability is not really good.

The CPU MAX of k1lsc is now 58-59. I remove the ODC block from k1lsc model for the simplification of the model.

The svn revision number of the model with ODC block is 2899 and 2900 is the one without ODC. This modification reduced the CPU MAX down to around 50, although the glitch did not go away.

After my dinner and short break, the 4 Hz glitch has gone. Yattane!!

No glitch in error signal of the single arm lock.
No glitch in PRMI error signal with ALS CARM locked.
And then, I misaligned the arms again, and the glitch has gone.

k1visetmyp also shows 58-59.
It's better to reduce something from etmyp.

itmxp, itmyp, and etmxp show 44, 44, and 47, respectively.
Is there some differences between the TypeA payload models?
Or does CPU_METER depend on the number of implemented filters?
Other suggestion is to delete unused filters.

I cleaned the foton file of ETMY up.

It reduce the CPU_METER
