<p><font face="serif">So due to us missing a day as a result of IRMA,
I am required by SACS to either have an additional class meeting
with you all or give you an exercise to be completed outside of
class. I think you all would prefer the out of class
exercise. It also gives me an opportunity to get you up to
speed on plotting -- which is going to be critical in the next
few weeks.</font></p>
<p><font face="serif">The dataset for HW 3 is now on the class
website. Your exercise is to PLOT this dataset using gnuplot
on cobra and to e-mail me a postscript file of the plot by <b>Friday
night at midnight</b>. To help you, I have provided an example
of how to use gnuplot to not only read and plot data, but how to
plot multiple data files on top of each other and produce a
postscript file. You will find this on the class web page in
the Examples section (at the top of the page).</font></p>
<p><font face="serif">You will have to make some small modifications
to this file that should be obvious (at this point you aren't
plotting your fit data, only the actual data). Make a file
containing these commands (like the example) and call it
something like "plotpoints". Save this on cobra in the same
location as the datafile.<br>
</font></p>
<p><font face="serif">Then, open gnuplot and run the file</font></p>
<tt>gnuplot</tt><tt><br>
</tt><tt>call "plotpoints"</tt><tt><br>
</tt><tt>exit</tt>
<p><font face="serif">If you are following my example, that should
create a file called plot.ps. <br>
</font></p>
<p>On cobra then type the command</p>
<p><tt>ps2pdf13 plot.ps plot.pdf</tt></p>
<p>to convert your file from a postscript file to a PDF file.
E-mail me the PDF file and the gnuplot file you used (your
plotpoints file) to create it.</p>
<p><br>
</p>
<p>If you have any questions or have difficulty with this let me
know. Friday afternoon and evening are going to be busy and my
turnaround time for questions near the actual due time will be
limited.</p>
