STRUCTURE OF CTPPS ALINGMENT XML FILE The file has the following structure <xml> <iov first="run:ls" last="run:ls"> <tag> <tag> ... </iov> <iov first="run:ls" last="run:ls"> ... </iov></xml> The time intervals are specified by the ‘first’ and ‘last’ run-lumisection pairs. If the <iov> tag is not present, an infinite validty is assumed for all the tags. The tag can be either "det" - the alignment correction is applied to one detector or "rp" - the alignment correction id applied to one RP Each tag must have an "id" attribute set. In addition the following attributes are recognized: sh_x - shift in x sh_x_e - the uncertainty of sh_x determination sh_y - shift in y sh_y_e - the uncertainty of sh_y determination sh_z - shift in z sh_z_e - the uncertainty of sh_z determination rot_x - rotation around x rot_x_e - the uncertainty of rot_x determination rot_y - rotation around y rot_y_e - the uncertainty of rot_y determination rot_z - rotation around z rot_z_e - the uncertainty of rot_z determination UNITS: shifts are in um, rotations are in mrad.
