CC       User-called
CC       Provides the user with information concerning the current status
CC          of the current minimization. Namely, it returns:
CC        FMIN: the best function value found so far
CC        FEDM: the estimated vertical distance remaining to minimum
CC        ERRDEF: the value of UP defining parameter uncertainties
CC        NPARI: the number of currently variable parameters
CC        NPARX: the highest (external) parameter number defined by user
CC        ISTAT: a status integer indicating how good is the covariance
CC           matrix:  0= not calculated at all
CC                    1= approximation only, not accurate
CC                    2= full matrix, but forced positive-definite
CC                    3= full accurate covariance matrix
