SHORT_TOLE

###
SHORT_TOLE

        The tolerance in position (in radians). The behaviour differ  for  Short
        and Zero spacings and  Table or 3-D cubes as Single-Dish data.

        If the Single-Dish data is a table of spectra, Spectra differing by less
        than this amount will be added together prior to gridding. A recommended
        value is below 1/10th of the Single Dish primary beam. This is valid for
        Short Spacings and Zero Spacing cases.

        If the Single-Dish data is 3-D data cube, SHORT_PTOLE is used  only  for
        Zero  Spacings.  If  no pixel is within SHORT_PTOLE of an Interferometer
        pointing center, no short spacing is added for this field and  an  error
        occur.

          Default  value  is 0, meaning using  1/16th of the Single Dish primary
        beam.
