Up to two characters can be packed into SORT with the second key to vary the fastest. Legal values in task UVSRT are: B => baseline number T => time order U => u spatial freq. coordinate V => v spatial freq. coordinate W => w spatial freq. coordinate R => baseline length. P => baseline position angle. X => descending ABS(u) Y => descending ABS(v) Z => ascending ABS(u) M => ascending ABS(v) For example SORT='XY' is required by UVMAP. Legal values in task DISKUSE are: U => sort by user B => sort by blocks used Null Value: ' ' Null value assignment varies with verb or task. ----------------------------------------------------------------
