With the help of Stuart's updates at LLO, I was able to implement several long-standing, yet minor changes to the QUAD models. The updates include:
(1) Increasing the number of violin mode damping filters at the penultimate stage from 10 to 40. The details and screenshots of this change can be found in Stuart's LLO aLOG 39539. Note, that this is only half of the ECR -- the other half was to remove the violin mode monitor BLRMS filters from the QUAD and install them in the OAF model. While they've been removed from the QUAD models, they have *not* yet been reincernated in the OAF model, because that model is currently over running its clock cycle turn-around time, and needs to be split. We must wait for some CDS software and hardware development (see/follow discussion in IIET Ticket 10520).

(2) Adding BLRMS to SUM channels for the optical levers. This is to allow for easier diagnosis of optical lever glitching. These require changes to the two QUAD library parts, in the L3 stage of 
    /opt/rtcds/userapps/release/sus/common/models/
        QUAD_MASTER.mdl
        QUAD_ITM_MASTER.mdl
A screen shot showing the copy-and-paste job for the optical lever sum is attached. These results in the following new channels in the frames,
    H1:SUS-${optic}_L3_OPLEV_BLRMS_S_${frequencyband}
where ${optic} = ITMX, ITMY, ETMX, or ETMY, and ${frequencyband} = 30M, 30M_100M, 100M_300M, 300M_1, 1_3, 3_10, 10_30, and 30_100 corresponding to the bands from 0 to 30 mHz, 30 to 100 mHz, 100 to 300 mHz, 300 mHz to 1 Hz, 1-3 Hz, 3-10 Hz, 10-30 Hz, and 30-100 Hz, e.g.
    H1:SUS-ETMY_L3_OPLEV_BLRMS_S_30M_100M

(3) Adding the top-level digitally summed output of ITM ESD drive to the frames at 16kHz, and adding the DC bias for the ITMs to the frames at 256 Hz. This is to facilitate deeper investigations into charge on the ITMs, and makes the storage of channels more like the ETMs.
    /opt/rtcds/userapps/release/sus/h1/models/
        h1susitmx.mdl
        h1susitmy.mdl
The new channels in frames are 
    H1:SUS-ITMX_L3_ESD_DC_OUT_DQ           256   
    H1:SUS-ITMX_L3_ESD_SUM_OUT_DQ        16384   
    H1:SUS-ITMY_L3_ESD_DC_OUT_DQ           256   
    H1:SUS-ITMY_L3_ESD_SUM_OUT_DQ        16384   
A similar screen shot showing the top-level modification to above mentioned models is also attached.

(1) was received upon update of the userapps repo (thanks Stuart!); the changes mentioned (2) and (3) have been commited to the userapps repo.
(2) and (3) are simply adding frame builder channels, so there're no necessary associated medm screen modifications.
