    		 Nearly perfect conditions: sunny, no clouds. Pointing drifts slightly, probably because the antenna is heating up in the sun. Tsys ~170K during scan No0001

    		 good weather. swapped pols, the setup will stay the same for c182a, but before c182b will be fixed.

    		 Tsys ~400K during scan No0001
    Ys Y Yes

    Fringes only to 'R'-channel:

    Only in scan No0009 fringess appear also to 'L'-channel

    		 An amplifier burned out, likely just before the test. Frontend signal switched to a spare channel to compensate, but too late to influence these results. This explains low SNR, but not why we see fringes to R only (Ys normally only records LCP at 3 mm, so both 'L' and 'R' should be the same LCP)
    Pv P Yes
