Notes

The source data file was «SCI180508_100617 - STRIP64_Tcryo_RF-40dBm_0101__08May2018.txt» (460 kB)

Reference temperature for the polarimeter has been set to 22.5K instead of 20K, to maintain its control during Y-Factor tests

High noise level is present on the detector output and this issue has been analyzed more deeply in two steady state tests.

Conclusion is that the behaviour could improve when using the actual chain without T-Magic, therefore with feed-horn and OMT.
