UV_TRACKS /SIZE

        [ASTRO\]UV_TRACKS ... /SIZE Size1 [NAntSize] [Size2 NAntSize2] [...]

    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.
