Array 1 (H, reflection) is NIKA2_1mm_MS_v3_10 - Al 25nm - LO 1.755 GHz

Array 3 (V, transmission) is NIKA2_1mm_MS_v3_05 - Al 22nm - LO 1.791 GHz

Please note that these frequency sweeps were taken in the C2 (CONCERTO2) cryostat under dark conditions. The cold amplifiers gains in C2 is not 100% homogeneous, explaining why some traces show higher transmission in the S21 plots.
