recomputation. Note that any data not selected are copied to the output dataset unchanged.
The following example changes the RA phase centre by 10 seconds of time and also corrects a delay error of -3 ns on antenna 2 (by adding a phase gradient across the band). uvedit has the option to turn off the recomputation of u and v which might otherwise be done ( options=nouv). This can be useful for say, entering a delay change (which does not need u and v to be recomputed) because MIRIAD does not compute u and v as accurately as the on-line ephemeris routines.
