2 HOW TO PICK
UP GRADED COURSEWORK AND
GET HELP WITH VOYAGER PROJECTS
GRADED VOYAGER PROJECTS AND
EXAMS: Graded projects and exams will be
distributed in class
the first week after
they were due or administered. The papers will be arranged in alphabetized stacks at
the front of the lecture hall. If you don't retrieve yours in
class, you must pick them up from the astronomy
Teaching Assistants during their office hours or by
VOYAGER HELP: The astronomy Teaching Assistants can assist
you with your Voyager 4 projects. Visit them during their office hours below, or else schedule appointments by
e-mail. If you have questions about the grading of a particular
project, the initials of the TA who graded it are written
next to your score on the back of the front page, so you
will know whom to ask.
ASTRONOMY TA OFFICE HOURS:
Office hours begin the second week of the semester. They
will not be held during breaks, holidays, and finals week.

obvious on the printout, then change its color (as
suggested in the first full paragraph on page 6 of your Voyager
4 project book). Examples: in Project 7, when you are ready to print
the Sky Charts, execute "Display / Colors..." and choose
black for the paths of the Sun and planets. In Project 14, execute "Display / Satellites
and Spacecraft...", highlight the Giotto segments, and click
on the colored square at top right to change the color to
black. Alternatively, just trace over hard-to-see
paths with a pencil.

of the page, remember to select "Deep Sky Objects" from the
pull-down menu in the Magnitude Limits dialog box before
dragging both magnitude sliders to 15.

use the same special "Startup file" as do the OSU lab
computers. To download a copy of it, click here. To install it, (a) move
the downloaded file to the same directory that contains the original
Startup file on your computer, (b) rename the original Startup file
as "StartupOLD", (c) rename the downloaded "Startup

extension for Windows, or delete it for Mac OS X. If
you then launch your copy of Voyager 4.5.7, it will open with a
WARNING: If you use your personal copy of Voyager to do your
Projects, you do so at your own
risk. Leave yourself enough time to complete the
Projects at one of the five computer labs listed in your Syllabus in
case you encounter problems with your own equipment.

go stargazing anywhere alone.
You may want to bring warm
clothing, binoculars, a (red) flashlight, constellation charts, a
blanket to sit on. Please carpool—parking at the

Explanations of the terms used in your individual Test Reports...
Score: This is set to
be the same number as the Percent Correct.
Percent Correct: The
percentage of questions you answered correctly.
Class Average: The
average Percent Correct of the entire class.
Class Median: Half the
class scored above this Percent Correct, half scored below
it. Usually the Class Median and Class Average are very
close. However, if the Average is higher than the Median,
that means a few individuals had very high scores. If the
Average is lower, then a few individuals had very low scores.
Percentile Ranking: The
percentage of the class that scored below you on the exam.

It shows how you stand compared to everyone
else on that one exam. Go to Section 6, the next section, to

COURSE GRADE HISTOGRAM
This histogram shows the
distribution of total points earned by students on coursework
through Project __ and the __ exam.
The current maximum possible point total is marked by the
rightmost "column" in the histogram.
"floors" for the various letter grades are shown in the graph,
and they reflect the standards in the Syllabus scaled to the
maximum number of points currently possible. Individuals' course grades
will be posted on SIS at the end of the semester.
To compute the points you earned on
each exam or project, multiply your Percent Correct by the item's
point value from the Syllabus. Examples:
A score of 80% on
a project worth 25 points yields 80% x 25 pts = 0.80 x 25 pts = 20
A score of 65% on
an exam worth 150 points yields 65% x 150 pts = 0.65 x 150 pts =
97.5 pts. The final exam is worth 300 points.
you've completed eleven or twelve Projects, include only the top
ten scores in your point total.
