Day 8

Well today I knew that I would be doing a lot of resizing. I realized yesterday that I had made a few mistakes when putting together the UV data images because I had not made them all the same number of pixels lengthwise and widthwise. I fixed my mistakes and went on to try to work with the infrared images I have. Brad explained that I needed to resize the infrared images so that it had the same number of pixels across and down as the UV images so that I could later place them on top of the UV ones. Tom helped me figure out how to resize the images according to the size parameters and such. By the end of the day I got the hang of it but was a little crushed to find out that because my infrared images were magnified so much Jake said not to resize the infrared images but only to resize the UV ones to fit the infrared ones. Tomorrow I have to go back to all of the individual fits files of the images resize them, save them as fits files again, then pull up the three images, far UV data, near UV data, and the visible infrared data, put each in a different color and place them all on top of one another and save it as a jpeg. Oh and there is some other part about setting their headers equal to each other, which is basically all the data of the images' dimensions, pixels, and whatnot. I think that's what I have to do, or at least that's how it's supposed to work, I'm sure I'll come up upon some problem where it won't work and I'll be down a completely different path tomorrow to get... well I don't know exactly what the end product is, but I guess when I'm done I'll find out, unless they have more work for me to do with these images, I already have a couple that I think will turn out really great. I feel like I've worked a lot today, even though technically I didn't get much done, I guess it's just because I must've tried almost 5 different ways to accomplish what I'm supposed to do and everytime I get thrown down a different path that says I need to do something else to achieve that one goal.
