We investigate the behavior of the new transient black hole candidate XTE J1118+480 using shot noise models in the time domain. Using light curves from the Unconventional Stellar Aspect experiment (USA), we model a portion of the emission as a superposition of shots. Individual structures in the light curve are fit to a template function. The results are compared to a similar analysis performed on light curves from Cygnus X-1. Results indicate that the characteristic timescale for XTE J1118+480 is around 3 times as long as for Cygnus X-1. [ABSTRACT FROM AUTHOR]
