    The size of the antennas can be customized with the /SIZE option.   With
    a  single  argument all the antennas are supposed to have the same size.
    Arrays with different antenna sizes can be defined using  several  pairs
    of  arguments. The first argument should be a size (in m) and the second
    the number of antennas of this size in the array. The sizes are  attrib-
    uted to the antenna in the order they are written in the command line.

    For  known  observatories (NOEMA, ALMA, ACA,...) the size of the antenna
    is already known, the /SIZE option can be used to use a different size.

    The size of the antenna is used to compute antenna shadowing.
