Galactic Modelling

0 Large parts of GRASP were developed using data from the Caltech 40-meter prototype detector. This detector is typically sensitive to distances of tens of kiloparsecs, roughly the length scale of our galaxy. It was therefore useful to develop a model of the galactic distributions of expected sources, for example, of the galactic distribution of binary star systems. This section contains a package of routines which can be used to simulate the expected distribution of binary inspiral sources in our galaxy. Because of the earth's motion about its axis and about the sun, the distribution of expected sources (direction, distance, orientation) changes as a function of time, with roughly a 24-hour period. This section constains routines which model the distribution of these parameters as a function of the earth's motion.
