  The Total Irradiance Monitor (TIM) from NASA's SOlar Radiation and Climate
Experiment (SORCE) can detect changes in the Total Solar Irradiance (TSI) to a
precision of 2 ppm, allowing observations of variations due to the largest
X-Class solar ares for the first time. Presented here is a robust algorithm for
determining the radiative output in the TIM TSI measurements, in both the
impulsive and gradual phases, for the four solar ares presented in Woods et al.
(2006), as well as an additional are measured on 2006 December 6. The radiative
outputs for both phases of these five ares are then compared to the Vacuum
Ultraviolet (VUV) irradiance output from the Flare Irradiance Spectral Model
(FISM) in order to derive an empirical relationship between the FISM VUV model
and the TIM TSI data output to estimate the TSI radiative output for eight
other X-Class ares. This model provides the basis for the bolometric energy
estimates for the solar ares analyzed in the Emslie et al. (2012) study.
