There are fringes for NOEMA at 104 GHz usingNOEMA104GHzwith the provided tunings. The 114 GHz part of the track, however, has no NOEMA fringes with the definitions as in the spreadsheet, nor with alternate approaches tried e.g. net sideband of the definitions flipped,channel order reversed (both with and without flipping the net sideband), very wide residual rate space (0.100s AP instead of 1.024s AP) and wide 2048-channel (+-16 usec) residual delay space. According to the spreadsheets, the 104G data and afterwards the 114G data originated from different PolyFix units, but the data were routed to the same Mark6 recorder3. Merely the cplane input_stream definitions were updated as necessary during the switch from 104 to 114 GHz. The lack of NOEMA 114 GHz fringes remains unexplained.
