    4 It is important to understand how measurements were collected to be able to interpret them.  The [wiki:OML ORBIT Measurement Framework] provides tools to insert points to tap available information and to effectively collect that information in a timely manner.  A number of different tools are available to interpret experimental results.  The choice of tools depends upon availability and the nature of the measurements.  Microsoft Excel can be used to analyze an experiment as shown in Figure 19 below.  Matlab can also be used.  Sample Matlab code is shown in Figure 20 and the resulting graph in Figure 21.

     4It is important to understand how measurements were collected and organized to be able to interpret them. The [wiki:OML ORBIT Measurement Framework] provides tools to insert points to tap available information and to effectively collect that information in a timely manner. And after the experiment is done, the user would get access to the exprimenet database generated. In general, the results of the experiment is in one [http://www.mysql.com MySQL] database. Different participating nodes populate different tables of this database. Usually, user would like to post-process or visualize those raw measurements for further analysis.
