Collected by me during the fall semester of 1998. The numbers refer to the actual questions in the ISP205L lab-book. The Earth is also an object a little smaller than Jupiter at a distance using angles to measure it's distance. It is easier to measure large objects using a conversion factor. This spectrum had thick colors in it that touched each other.
Some lines are thicker than others and some have more lines.
It appears as though there are more lines, but these are just colors. Oxygen is a gas that flows east to west in the atmosphere. So it stays level in the atmosphere it doesn't sway. The oxygen is not moving toward us or away from us, it just exists in the atmosphere. The oxygen is the earths atmosphere and we are looking through it because of the Doppler shift.
