\caption{Tests of the ISHAPE profile-fitting algorithm. For each
  combination of input parameters ($V=20/21/22$, {\it FWHM} $=1$ pc/2 pc)
  the output fitted {\it FWHM} and $\alpha$ parameters are 
  shown for three initial guesses of $\alpha$ ($\alpha_0 = 1.0/1.5/2.0$).
  Numbers in parentheses denote the object-to-object \rms\ deviation 
  around the mean values, excluding the two most deviating points at 
  each extreme.
