This week I moved ZM3 by 8mm (see alog 61671 and 61593) following which we started performing beam alignment work on ZM2 and ZM3 in HAM7 chamber. Since we mechanically adjusted ZM2 and ZM3 for both pitch and yaw, hence it is wise to take transfer function to rule out if any EQ stops are rubbing.

The plots attached below confirms that ZM2 and ZM3 are free of any rubbing and are healthy.

The templates are stored at the following location,
