UK Schmidt has huge AO, ~ AAT/2dF or SLOAN
Galaxy source counts inversely with brightness
=> same number of accessible targets per unit time for given AO
Schmidt has unique ability to cover whole sky
So ideal for wide field, shallow samples, in particular new wavebands or techniques.
And also ideal for peculiar velocities.
6dF coincides with first imaging and first NIR sky surveys - 2MASS, DENIS.
Ending of photographic era allows large fraction of UKST time to go to 6dF
