Notes

The source data file was «SCI180717_130828 - STRIP25_OMT_0110_rectan_horn_300_77K_congrid_vert_e senza_17jul2018.txt» (304 kB)

in this test we put 77K in front of feed horn. the we put the polarization grid between the load and ther horn with vertical wires that should reflect in the horn a mix of polarimeter noise and surrounding ambient temperature.
Successively with the grid in the same position we put 300K load behind the grid and than we remove the grid
