| (3)Date of coil calibration (measurement in the calibration magnet). | |||||||||
| (4)Total number of turns in the coil. | |||||||||
| (5)Width of the coil former (inside the winding) from construction drawings. | |||||||||
| (6)Length of the coil former (inside the winding) from construction drawings. | |||||||||
| (7)Thickness of the winding groove in the coil former from construction drawings. | |||||||||
| (8)Coil cross section as measured in the calibration magnet. | |||||||||
| (9)Relative difference of cross sections among the coils in a section with respect to a reference coil (usually C), | |||||||||
| computed based on the measured surface of each coil. | |||||||||
| (10)Obtained as the difference of measurements of the coil former before winding and of the coil after winding. | |||||||||
| Leave blank if not available. | |||||||||
| (11)Measured in the calibration magnet or derived from construction drawing. | |||||||||
| (12)Measured in the calibration magnet or derived from construction drawing. | |||||||||
