Notes

The source data file was «SCI170614_091447 - STRIP10_Y-Factor_LB_40K_down_50-40-30-20-10_PS0110_14Jun2017.txt» (1907 kB)

At high LB temperatures it has not been possible to maintain polarimeter temperature at 20K (no more control available of the temperature by mean of its heater, already at zero output power).
Actual polarimeter temperature was 20.4 and 20.8K with loadB respectively at 40 and 50K
