Fixing parameters

    For fixing parameters there are different possibilities:

• you can can enter a blanc or ``0''. In the parameter list in the column ``error''
              
       2     asy_tot     0.23     0.     0.20     0.30            or

• you can define the parameter which should be constant under SIGNAL commands using the redefinition parameter 201....
             
       SIGNAL   , 201,    ,   #,
       asy_tot=0.23                  or

• you have another chance to fix the parameter while running MINUIT. Using the command FIX < param# > will fix the parameter at its current value. The paramter will return to variable status by entering RELEASE < param# >. The command CONTOUR <para1> <para2> only varies the parameters <para1> and <para2> while fixing all the others at their current value.
