| res.cv_cntr | scalar | one or multiple instances of this quantity can be referenced elsewhere in the input file. these quantities will named with the arguments of the bias followed by the character string _cntr. These quantities give the instantaneous position of the center of the harmonic potential. This particular component measures this quantity for the input CV named cv |
| res.cv_work | scalar | one or multiple instances of this quantity can be referenced elsewhere in the input file. These quantities will named with the arguments of the bias followed by the character string _work. These quantities tell the user how much work has been done by the potential in dragging the system along the various colvar axis. This particular component measures this quantity for the input CV named cv |
| res.cv_kappa | scalar | one or multiple instances of this quantity can be referenced elsewhere in the input file. These quantities will named with the arguments of the bias followed by the character string _kappa. These quantities tell the user the time dependent value of kappa. This particular component measures this quantity for the input CV named cv |
| res.work | scalar | the total work performed changing this restraint |
