<p>
Since LTPDA is an object-oriented system, the user must create objects of different
types using the appropriate constructors. The various constructor forms for each
different LTPDA class can be explored using the <it>constructor helper</it>.
</p>
<p>
To start the constructor helper GUI:
</p>
<div class="fragment"><pre>
>> ltpda_constructor_helper
</pre></div>
<p>
or click the appropriate button on the Launch Bay.
</p>
<p>
You should then be presented with the following figure:

<br>
<br>
<p>
Selecting a class from the drop-down list reveals the possible parameter sets for that
class constructor. Selecting a parameter set reveals the default parameter list constructor
string for constructing that class object in this way. For example, if we want to construct
and Analysis Object using the time-series constructor, select the AO class then click on
"From Time-series Function". You should then see:
</p>

<p>
You can then edit the parameter list and build the object by clicking on <tt>Build</tt>.
