Skydip Observations with EMIR
General Procedure: two skydips are performed in both bands E1 & E2. The central frequency for each band is set to 151.60 GHz USB and 256.68 GHz USB (average of A1 & A3) after calculations of the effective frequency for the NIKA2 bands by J. Macias (A1 => 255.53 GHz, A2 => 151.60 GHZ, A3 => 257.84). The recorded bands are 4 BBCs (LSB & USB in HORIZONTAL & VERTICAL polarizations) and 2 NBC (USB in HORIZONTAL & VERTICAL polarizations). The scans are reduced in MIRA following the procedure outlined here. Opacity results are given in the plots.
2017-02-22, Skydip Azimuth = 134.05°: weather conditions were very similar for both measurements with pwv ~ 7 [mm]. A pointing (dAz = 3.7", dEl = 6.1") and focus (dFz = -2.0 mm) was performed on Mars to check the EMIR settings. Scan numbers for the bands are: 26, 28 for E1 and 32, 34 for E2. WARNING: the E2 frequency used in this day was 256.0 GHz instead of 256.68 GHz due to a typo in the NIKA2.lin file.
Results: E1, s26 here. E1, s28 here. E2, s32 here. E2, s34 here
2017-02-25, Skydip Azimuth = 128.70°: weather conditions for both measurements with pwv ~ 3 [mm] but VERY UNSTABLE. A pointing (dAz = 4.0", dEl = -1.0") and focus (dFz = -2.4 mm) was performed on Jupiter to check the EMIR settings. A focus was done after the skydip measurements to check that the focus correction first applied using the E2 tuning was also adequate for E1 (dFz = -2.5 mm, consistent). Scan numbers for the bands are: 16, 18 for E1 and 11, 13 for E2.
