Text file containing throughput measurements for each waveguide of the ULI reformatter at 1550 nm. For each waveguide the polarisation was varied and the maximum and minimum throughput (in dBm) is recorded. X position and Y position (in mm) identifies the input position of the measured waveguide. Reference input is the max and min power (in dBm) measured out of the fibre used as the test input, used to determine the throughput of the reformatter.
