SET TRIANGLE

        CLIC\SET TRIANGLE t1 t2 ... PHYSICAL|LOGICAL

    Selects the triangle products for which data will be  displayed  by com-
    mand  PLOT.  Valid  triangles are codes as e.g. "123"  or  "345".   This
    command is exclusive with commands  SET  BASELINES  and SET  ANTENNAS.

    This  command  will be effective only if the triangle products have been
    computed and stored in the data by commands  SPECTRUM/TRIANGLE  or  COM-
    PRESS/TRIANGLE.  In that case the triangle products will have been aver-
    aged by these commands; since the phase of  the  triangle  products  are
    closure  quantities, the amplitude of the average should not be affected
    by atmospheric decorrelation.
