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.
