Non-standard modes are observing modes that are less well characterized or for which the data need to be processed manually by ALMA staff. Up to 25% of the total Cycle 3 observing time will be assigned to such projects. Non-standard modes are supported in Cycle 3 on a "best-efforts" basis only. Non-standard modes are:
-
Bands 8, 9 & 10 observations
-
Long baselines (> 2km)
-
Polarization
-
Spectral Scans
-
Spectral setups with only narrow band spectral windows (aggregate bandwidth < 934 MHz)
-
Non-standard calibrations (user-defined calibrations selected in the OT)
