The Bristol algorithm is conceptually similar to the Bootstrap algorithm; i
t uses the fact that 3-d scatter plots of Tb tend to lie in a plane. However, in
stead of viewing the data in a Tb(37v), Tb(37h) plane as the Bootstrap does, the
Bristol views the data perpindicular to the plane. The Bristol uses coordinate
axes of:
Tb(37v)+1.045*Tb(37h)+0.525*Tb(19v) and 0.9164*Tb(19v)-Tb(37v)+0.4965*Tb(37h)
Because the retrieval region is larger than Bootstrap, the Bristol algorithm is
in theory less noisy and more stable.
