DataCollection: DataforthisanalysiswascollectedusingtheSloanDigitalSky Survey(SDSS),whichisanimagingandspectroscopicsurveyofa largeportionofthesky.Thesurveycontains2Dimagesand spectraofover500millioncelestialobjects,includinggalaxies. UsingtheSDSS,wewereabletoobtainimagesandspectraofthe WaterVeinHostGalaxySystem.Theimageswereanalyzedto determinetheinclinationangleofthehostgalaxy.
