_FOR EACH SIMULATION_

```

      NAMES <time_series_names>

#### Explanation of Variables

##### Block: ATTRIBUTES

  * `NAMES` xxx

  * `time_series_names` Name by which a package references a particular time-array series. The name must be unique among all time-array series used in a package.

  * `METHODS` xxx

  * `interpolation_method` Interpolation method, which is either STEPWISE or LINEAR.

  * `METHOD` xxx

  * `interpolation_method_single` Interpolation method, which is either STEPWISE or LINEAR.

  * `SFACS` xxx

  * `sfacval` Scale factor, which will multiply all array values in time series. SFAC is an optional attribute; if omitted, SFAC = 1.0.

  * `SFAC` xxx

##### Block: TIMESERIES

  * `ts_time` A numeric time relative to the start of the simulation, in the time unit used in the simulation. Times must be strictly increasing.

  * `ts_array` A 2-D array of numeric, floating-point values, or a constant value, readable by the U2DREL array-reading utility.
