So now you’re at that step to begin looking at the data that you just processed into the augustine system.  To do so, first open a new Terminal and log in to your account using the login procedure.

##First, access the root directory

% cd /

## access the pal directory, and in the pal directory the access the fieldcamp directory from whatever year you need to access.  In this case, year 2011 is being accessed.

% cd pal/fieldcamp/2011

Next, in the 2011 directory, the passive_seismic folder should be accessed.  Within passive_seismic is the data directory.

% cd pal/fieldcamp/2011/passive_seismic/data

Now, once this folder is accessed, it is now time to use datascope commands to access the seismic data.  The first step is to run the database window, which is the general tool for navigating through the relational database.  Because this window as well as the seismic database window will be running simultaneously, run this first window, dbe, in the background:

% dbe neal_HS &

Once this is completed, one can now use the dbpick command to pull up the data.

% dbpick -ts 2011180:00:00:00 -nostarttalk -t 3600 -sc ‘*:EHZ’ neal_HS

So right now you should have a rectangular dialog box and a square dbpick window that includes your data.  With the above command, the time of the data begins on the 180th Julian Day of 2011.  the 3600 stands for the amount of seconds displayed in the dbpick window at one time.  The ‘*:EHZ’ stands for the channel and the Z component.  to pull up all three components, E,N, and Z, use the command:

‘*’

Now it’s time to navigate through dbpick.  The P-wave arrivals should be flagged, which correspond to earthquakes in the NEIC database that can be accessed by pressing the origin button in the dbe dialog box.  To find the events, first press f, which finds the first event in the database, and from there press n to proceed to the next event, or p to go back to a previous event in dbpick window.  You can also use the scroll on the bottom of that window to scroll through the seismic data.

An interesting feature in the origin window is that the earthquakes have their longitudes and latitudes listed, which are used in located the source of the earthquake.  Go to Graphics and press Map and the earthquake location is present on a map.  Toggling in and out is also possible when using this map.
