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.
4 PROJECT NEWS AND TIPS
Please refer to Section 4 in your
Syllabus for complete information about doing your Voyager 4
a planet, path, etc. is visible on your monitor but not
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.
purchase a personal copy of Voyager 4 for your own
computer, it must be version 4.5.7.
purchase it. Also, you must
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
copy" file as "Startup", and (d) retain the file's ".vgr"
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 four computer labs listed in your Syllabus in
case you encounter problems with your own equipment.
WARNING: Microsoft is now working on a fix for a bug in
its Fall 2017 release of Windows 10 that affects programs
including Voyager 4. Earlier versions of Windows do not
have that problem.
4 STAR PARTIES
Optional sky viewings may be scheduled from time to time on
campus or at OSU's observatory (see below).
dark spot for stargazing whenever you wish is the small, gravel
parking area at Lake Carl Blackwell marked by the red rectangle on
this map. Never
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
observatory is limited (six spaces)! The drive from Koby Plaza
(map below) takes about 15 minutes. Drivers should check their

near observatory (result of Saturday's rainfall) and possible
Tuesday evening clouds/rain.
Meet at the Koby Plaza parking lot by its sign, 1/4
mile west of intersection of Sangre Road and West 6th Avenue
(north side of road). We will carpool to the observing site
(about 15 minutes).
We will depart no later than _______. The actual
viewing should last about _______.
5 EXAM RESULTS
In your individual Student Grade Report, Score (%) is
the percentage of questions you answered correctly. This
represented graphically by the length of the horizontal, shaded bar
to the right of your score number. The class average is marked
by the short, vertical black line in the shaded bar.
Here is the histogram for the most recent
It shows how you stand compared to everyone
else who took that exam. Go to Section 6, the next section,
to see how you compare to everyone else on the basis of all exams
and Voyager projects to date.
Here are the answer keys for the final exam (no
longer in invisible ink!):

Form B: CBB BCB ACA ADA BCA BDD ACA DAD DCA

COURSE GRADE HISTOGRAM
This histogram shows the
distribution of total points earned by students on coursework
through Project 3 and the final 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.

Section 3 (Exams) of your syllabus!
