SHORT_UV_MAX

    REAL number: No visibility at spacings higher than  SHORT_UV_MAX  is  gener-
    ated. Theoretical consideration on the method used in this task implies that
    SHORT_UV_MAX  should be at most (SHORT_SD_DIAM-SHORT_IP_DIAM).  Smaller val-
    ues may need to be applied if, for example, the  pointing  accuracy  of  the
    Single Dish is insufficient.

      Default value is 0, meaning to use SHORT_SD_DIAM-SHORT_IP_DIAM
