2 MINOS
  Syntax: MINOS [pars]
   where: pars  is a list of parameters

  Calculates the MINOS  errors for the list of  parameters given. If you
  omit  the list  of   parameters, the  errors  are  calculated  for all
  floating parameters.  The maximum number of  calls can be set with the
  `MAX_CALLS' command.

  Note  that  when the   external  covariance  matrix  gets  printed the
  off-diagonal   elements  are the   correlation   coefficients, not the
  elements of the matrix:

  C(i,j) = V(i,j) / sqrt(V(i,i)*V(j,j)).

  The diagonal elements are the parabolic errors.

  If you make a plot of your fit parameter with MINOS errors and then
  you want to store the histogram, you should not use the `STORE'
  command, as HBOOK does not know about asymmetric errors in its normal
  histograms. Instead use the `DAT_STORE' or `MN_STORE' commands that
  write the plots out in an ascii file or in Mn_Fit format.
