A note on Mad City Labs products for ISC persons
MCL PZTs used for ALS injection alignment on the ISCTEX|Y have strange convention.
X=PIT (rotation around X or horizontal axis)
Y=YAW (rotation around Y or vertical axis)
Also the gain of the internal feedback is set to the highest, which seems to cause a large oscillation for 2" optic. You need to open the chassis and move the jumper to reduce the bandwidth.
