MODIFY DELAY

        CLIC\MODIFY  DELAY a1 d1  [a2 d2 ...] [/OFFSET] [/IF if] [/BBAND ib]
    [/ALL] [/INSTRUMENTAL] [/POLARISATION H|V|BOTH] [/SWITCH DIRECT|CROSSED]

    Modify the delay for  antenna  a1  to  be d1 (nanoseconds), and   recom-
    pute the  phases  accordingly.

    Use  option  /OFFSET to enter delay changes with respect to the previous
    values.

    Option /IF or /BBAND allow to modify the delay for a given IF  or  base-
    band.  Option /ALL modify all spectral windows.

    Option  /INSTRUMENTAL allows to correct a delay that would have been in-
    troduced in the system after mixing with LO1, i.e. in IF1.

    Option /SWITCH allows to correct only baselines where the  antennas  are
    in the direct/crossed state.
