The `MSE`

object has 29 slots. As it is an S4 object the slots are accessed with the `@`

symbol, e.g., `MSE@Name`

.

### Name

Name of the MSE object. Single value. Character string

### nyears

The number of years for the historical simulation. Single value. Positive integer

### proyears

The number of years for the projections - closed loop simulations. Single value. Positive integer

### nMPs

Number of management procedures simulation tested. Single value. Positive integer.

### MPs

The names of the MPs that were tested. Vector of length nMPs. Character strings.

### nsim

Number of simulations. Single value. Positive integer

### OM

Operating model parameters (last historical year used for time-varying parameters). Data.frame with nsim rows

### Obs

Observation parameters (last historical year used for time-varying parameters). Data.frame with nsim rows
