| Notes | The source data file was «SCI180119_132713 - STRIP25_Y-Factor__upLB-40K_10-15-20-25-30-35-40-45-50_PS0101_V4_reduced_19Jan2018.txt» (3019 kB) The step 30-35K has reached hardly the proper final steady state, because there has been an initial mistake setting the 35K temperature, with a starting value at 38K, correction and consequent oscillation. Moreover, temperature step 45-50 has not been rcorded properly, it is not reliable and has not been presented. Results are bad and substantially not significant, especially for the two detectors that should be blind for the relevant position of phase switches. Offset of detectors at P=0 showed to be substantially constant during the execution of tests. |
