Two - Point Angular Correlation Function )

The Two Point Angular Correlation Function (TPACF) is a mathematical equation that has applications in many areas. In our project, the Two Point Angular Correlation Function is used as a way to measure the probability of finding an astronomical body at a given angular distance from another astronomical body. We were given working sequential code as a starting point. The sequential code took in two kinds of data to process. The first consisted of a set of valid data points measured from a region of space. These data points represented the spherical coordinates of actual astronomical objects in space. The number of data points that this set contained could range up to 97,178 data points. The second kind of data was randomly generated data. The randomly generated data sets contained coordinates similar to the actual data set, but with random distribution. The number of random sets used varied and could be set with an input parameter, but each set must contain at least the same amount of points as data points being used. It is not uncommon to run the TPACF program with as many as 100 random data sets.
