I updated the filters on the quad test stand ( /cvs/cds/llo/chans/L1QTS.txt ) with the set from the file of the same name and location at LLO. (Due to the recent upgrade at LLO, the working set there is actually /opt/rtcds/tst/x2/chans/X2SUSQTS.txt which is functionally identical but has been conformed to a new naming convention that has not yet been brought in at LHO.) The old filters are archived at cvs/cds/llo/chans/L1QTS_LHO_20101117.txt . The new filters correspond to the electronics at the sites, which is different from that at LASTI. Derek Bridges has summarized the filters as follows: 

Input filters (both chains, all OSEMs):
1. "10:0.4" - zero at 10 Hz, pole at 0.4 Hz - zpk([10],[0.4],1,"n")

Output filters (both chains, all OSEMs):
1. "1:31" - zero at 1 Hz, pole at 31 Hz - zpk([1],[31],1,"n")

DOF filters:
M0-X:
1. "0:15,15" - zpk([0],[15;15],1,"n") [the rest are similar with 15
replaced by 20 or 25]
2. "0.43Boost" - zpk([0.428;0.428],[0.1427+i*0.4035;0.1427-i*0.4035],1,"n")

M0-Y:
1. "0:15,15"

M0-Z:
1. "0:20,20"

M0-Yaw:
1. "0:20,20"

M0-Pitch:
1. "0:25,25"
2. "0.54Boost" -
zpk([0.324+i*0.432;0.324-i*0.432],[0.108+i*0.5291;0.108-i*0.5291],1,"n")
3. "1.13Boost" -
zpk([0.78+i*1.04;0.78-i*1.04],[0.26+i*1.2737;0.26-i*1.2737],1,"n")

M0-Roll:
1. "0:20,20"

R0-X:
1. "0:15,15"
2. "0.43Boost" - zpk([0.428;0.428],[0.1427+i*0.4035;0.1427-i*0.4035],1,"n")

R0-Y:
1. "0:20,20"

R0-Z:
1. "0:20,20"

R0-Yaw:
1. "0:20,20"

R0-Pitch:
1. "0:25,25"

R0-Roll:
1. "0:20,20"

Both chains, all DOFs:
10. "Ellip50"
