We discovered yesterday that the flag of the side OSEM on the first stage of the IMC triple suspension was hitting the top of the OSEM hole. Betsy moved the OSEM and it should now be free.
However, this should mainly affect the roll motion of the mirror. It did not fix the problem with the IMC1 alignment. 

The alignment problem turned out to be just a confusion between calibrated and non-calibrated data (thanks Jeff). The IMC mirrors were never misaligned. 

However, that puts the blame for the misalignment into the IMC squarely on the beam coming from the PSL table. This is something we need to keep monitoring and fix today.
