    102 Note that only 100 parameters may be included in a constraint,
    103 with one exception. When shifts for Uiso for all atoms in a phase
    104 are constrained, this counts as a single parameter. If more than 100

     105Note that only 100 parameters may be included in a single atomic constraint,

     107are constrained to the same value for all atoms in a phase,
     108this counts as a single parameter. If more than 100
    105109parameters are entered for a constraint, an error message is shown.
    106 Up to 2000 atomic constraints may be entered.
     110Up to 2000 total atomic constraints may be entered.
    107111EXPGUI does not warn if you exceed this limit.

     182Note that only 27 terms can be included in a single profile constraint.
     183Also, only like profile terms can be constrained. While GSAS does allow
     184different types of profile terms to be constrained together, this does not
     185usually make sense and EXPGUI does not allow it.
