The polarization of the supermendur foils was measured by motor scanning of the magnetic flux through the foil.
The following table contains the parameters of the foils considered. Some of these foils have been early installed at SLAC Moller polarimeter and were recalibrated. A detailed summary of the foil dimensions, weight, polarization values for different magnetizing fields are listed in Table.
