Notes/discoveries following meeting
-----------------------------------

1) Rotation in OPAL
   This was done with the OPAL frames UPSIDE DOWN with respect to the CMS case.
   See attachments 'Rotation on OPAL', 'Rotation on CMS'. 
   'Rotation on OPAL' also shows the connections to the crane from the 4 OPAL frame feet.
   
2) Mario will calculate a quick C of G possibly by tomorrow, 4 May.

3) Mario agreed with alexander, a 20mm spacer is forseen between the stiffening beam and the
   connection to the blue feet.

   Another spacer exists between the stiffening beam and the backplate.
