The parameters in param_obs0x.txt files are as follows for two demos:

Demo 1: In this Demo, the parameters for each trial are considered to be constant during the course of the task. Each observation parameter matrix is as:
	[s(x).p.b s(x).p.E s(x).p.D s(x).p.A [s(x).angle;s(x).scaling]]

Demo 2: In this Demo, the parameters can change over time. Each observation parameter matrix is as:
	[s(x).p.b s(x).p.E s(x).p.D s(x).p.A s(x).p.invA]
	Each row corresponds to task parameters for different candidate frames.
