| If you would like to see how one of the video files looks, you may download one of the certification files. It is an avi file and may be viewed using the Windows Media Player. You'll want to save it to your hard drive first, since it's a large file (12 MB). Note: The format of this downloaded AVI file is Indeo Video 5.10. The MS Windows Media Player supports this format but the Apple’s Quick Time Player does not. If you have Windows 98/2000/ME, you may want to update to MS Windows Media Player 7.1. You may download it free from the MS web site (Do not update to MS Windows Media Player 7.1 if you are using Windows 95 or NT4.0). You may get the update at the web site http://www.microsoft.com/windows/windowsmedia/en/default.asp Just RIGHT click to DOWNLOAD then choose "save link as" or "save target as" and save it to your hard drive. Once the file is saved, you may then view the saved AVI file using the Windows Media Player or any other video viewer that supports the Indeo AVI format. This video is a digitized time lapse recording of the moon on January 3, 2001 between 3:12 to 3:39 PM at Point Mugu Naval Air Station California. The landmass most to the right is Point Mugu. This videotape is a sample of my documentation of using a camera to make angular measurements. The moon’s angle above the horizon goes from about 32 degrees to 37.3 degrees during this videotaping. I have also superimposed an electronic degree template. The middle horizontal long line across the screen is equal to 18 degrees from the most bottom long tick mark that is just above the water line. The most top long tick mark is 36 degrees. Each tick mark on the video screen is equal to 1 degree. The longer tick marks are even number of degrees. The most bottom longer tick mark nearest the water line is about 2/10 tenths of a degree above the horizon. This means that you would add .2 degrees to the tick marks to get the corrected camcorder measured value of the moon’s elevation angle. I’ve made a copy of the Naval Observatory’s moon data for this videotape’s date, time, and location. I put it here so you may compare the camcorders angular measurements with the US Naval Observatory’s data. I think they agree within 1/10 tenth of a degree of each other. An accuracy of 1 degree would be sufficient for the Lowflying Aircraft Monitoring System. POINT MUGU, CALIFORNIA
