... Less than 1% of 20cm observing time would be lost to bad weather. ... Over the winters of 2002-2004, the so-called "swap" scheme has been used to give 3mm observers some robustness to poor weather. With this scheme, a pair of 3mm and centimetre proposals are partnered and scheduled typically a few days apart. At the discretion of the 3mm observer, the order of the 3mm and centimetre proposal can be swapped to give the 3mm observer the best chance at good weather. ...
