First Last - Plotting

The file SDSS_MainBelt.csv contains data on objects in the asteroid belt collected by the Sloan Digital Sky Survey.

The columns are:

• Name - Object name
• a - semi-major axis
• cA - SDSS a$^*$ color
• cI - SDSS i color (near infrared)
• cZ - SDSS z color (infrared)
• X - X position [au] - Sun-centered coords (10/29/2014)
• Y - Y position [au] - Sun-centered coords (10/29/2014)
• Z - Z position [au] - Sun-centered coords (10/29/2014)

The Kirkwood Gaps - Mean Motion Resonances

• Orbital period [years]: P = a ** (3/2)
• Orbital Period of Jupiter: Pjup = 11.8618 years
• Make a histogram of: (Pjup / P)
• Bins = 150
• Invert the x-axis
• Draw vertical lines at (Pjup / P) = 1,2,3,4
• Label the axis
• Output size w:12in, h:8in
• Make the plot look nice (including clear labels)

The Position of the Asteroids

• Make a 3D plot of X vs Y vs Z for the asteroids
• Orient the plot so you can see the 3D structure of the asteroid belt
• Output size w:9in, h:9in
• Make the plot look nice

The Color of the Asteroids

• Make three (3) plots in one row
• In each panel, plot a histogram of the semi-major axis (a) for all of the asteroids.
• Bins = 100.
• Only show 2.0 AU < a < 3.6 AU
• In the first panel, overplot a histogram of a for C-Type asteroids only.
• In the first panel, overplot a histogram of a for S-Type asteroids only.
• In the first panel, overplot a histogram of a for V-Type asteroids only.
• In each panel, draw a vertical line at a = mean(a) for that type of asteroid.
• Adjust the color and transparency of the overplotted histograms so that it is easy to see.
• The asteroid types can be determined from their colors (see image below).
• Output size w:15in, h:5in
• Make the plot look nice (including clear labels)

Trojan Asteroids

• Trojan asteroid have a > 5.0 AU
• Make a pie plot with 3 pieces
• Each piece should represent the percentage of each asteroid type in the trojan population
• Output size w:8in, h:8in
• Make the plots look nice (clear labels)
