Astronomy Lab report (reasonable bid will be accepted)

Choose 3 experiments  from the list of applets(part 3), explore experiments, write  3  lab reports, answering questions given for each applet . Format of  lab report you can see in Lab report example.
( applets simulation screen shots should be included into lab report )
 
After  clicking on applet it may ask  to install flash plugin. You should agree and install. Different applets may need different plugins.
I am grading quality of  answers to questions given for each experiment. Please follow the format of provided example for lab report.
Based on some theoretical knowledge (that you put into report) you should draw some predictions and based on data taken from simulator (please provide screen shots) you should shape your data into tables and graph plots.
and in conclusion discuss, if your predictions are confirmed by experiment.
You should write  different reports, separate for each experiment, but they could be combined in the same file.

List of applets(part 3)

Dark matter mass (https://foothill.edu/astronomy/astrosims/dark-matter/) 

Changing the distribution of dark matter as function of radius find the best fit

For Milky way;
average of all statistics  from all galaxies
galaxy with highest orbital velocity
galaxy with lowest orbital velocity

Transit simulation     (http://astronomy.beamappzone.com/# ) 

For all presets measure the fraction of transit time to period.                     

Changing system orientation find parameters corresponding to largest fraction of transit time               
for 3 presets:

TrES-1
Xo-1b
OGLE-TR-111b

 Milky Way Viewer .(http://physics.unm.edu/Courses/Rand/applets/milkyway.html)

         Define, describe shape of distribution and location in the galaxy for

Population I stars
Population II stars
Galactic bar
Open Star Clusters
Globular Star clusters
Gaseous nebulae  

Cosmology (http://highered.mheducation.com/olcweb/cgi/pluginpop.cgi?it=swf::800::600::/sites/dl/free/0072482621/78780/Cosmo_Nav.swf::Cosmology)

If universe would  have  (Links to an external site.)Links to an external site.=1.7 What Hubble constant  will make universe oscillations equal to 14 billion years ?
If universe would  have  (Links to an external site.)Links to an external site.=0.5.  What the ratio of universe size would be at the age of 14 billion year  if Hubble constant is changing from 235 km/s/mps to 25 km/s/mpc

Universe simulation  (http://chrisnorth.github.io/planckapps/Simulator/#) 

For normal matter fraction 0.2, 0.6, 0.8 charging fraction of dark matter and Dark energy, please find parameters to have simulated universe most close to observation of our universe.

Rotation curve (https://pages.pomona.edu/~tmoore/RotCurve/)

For NGC2403, M33, UGC128  changing Halo Density, Halo Radius and Dark Matter fraction, find the best parameters which give best approximation to observed curve.
