| Notes | The source data file was «SCI180122_143620 - STRIP20_Y-Factor__downLB-40K_50-40-30-20-10_PS0110_V3_22Jan2018.txt» (2367 kB) It has been necessary to decrease the temperature reference on the cross guide from 15 to 10K, to maintain the 20K control on the polarimeter during during the variations of the load temperature. Results should be in general considered with caution, because the legs are strongly unbalanced, especially the ones relevant to the detectors that should be “blind” |
