# PeerNGAMotion

This command is used to construct a TimeSeries object which, similar to a Path TimeSeries, the load factor obtained is dependent on a series of points obtained from a file. The difference is that the file is obtained from the Peer NGA strong motion database using an internet connection.

```tcl timeSeries PeerNGAMotion $tag $eqMotion $factor <-dT $dT> <-NPTS $nPts> ```

tag

unique tag among TimeSeries objects.

eqMotion

the PEER NGA name of the motion (a string containing the earthquake name, station & dirn)

factor

factor to be applied to the data points, if accel record type you want to specify G

nPts

optional, if provided will set the variable nPts equal to number of data points found in record

dT

optional, if provided will set the variable dT equal to time interval between points in the record

NOTES:

EXAMPLE

To create 2 time series for two horizontal motions recorded for the Borrego Mtn 1968-04-09 earthquake recorded at the USGS 117 El Centro Array #9 station

timeSeries PeerNGAMotion 1 /BORREGO/A-ELC180 $G -dT dt -NPTS nPts

timeSeries PeerNGAMotion 2 /BORREGO/A-ELC270 $G
