For the GLIMPSE
 project, I created a catalog of images of known ultra compact H II regions. I first made tri color images of the region to get 
 an idea of the shape using the one, two, and four wavelength channels in blue, green, and red respectively. I also created images
 of the regions in gray scale in channels one and two. I zoomed in on the ultra compact HII region and adjusted the contrast so
 that the brightness of the region would not overpower the image. In some instances I made duplicate images, one with a brighter
 contrast and another with a fainter contrast to make the area more visible. These images are sometimes denoted with b for bright
 and f for faint to distinguish between the two files. The images were named based on their approximate galactic degree system 
 coordinates followed by a _1 or _2 to denote which channel was used.
