Confused about Camera

[AnkurG]

Ok, a few days ago our lead programmer and I tried calibrating our camera for green. We placed it under a 1000 watt mercury vapor lamp (our teacher had one lying around...don't ask). We followed the instructions for calibration which were to grab a frame and click on green and let it calibrate and we would get an exposure value. We received a value of 15, which our programmer placed into the code where the exposure values should be placed. After that we loaded the code onto the OI and we were tracking green succesfully. Today I tried to calibrate for yellow. Nothing was working. It could not find it for any reason. We did get one exposure value of 57 at one point, but could not get it again. After searching around on the forums I found out that you can select the color and highlight it in the picture and you will get corresponding RGB values. But this is not the exposure value, so where in the code would these values be placed. Also I found out that Dave Lavery said that each event will give us the calibration numbers for each location at the event. Now what numbers do they give us? The exposure values or the RGB values? If anyone can tell me a surefire way to calibrate the camera properly and where to place the values that we receive into the code, please tell me. Any help would be appreciated.
