Fitting to Only Velocity Data

Step Size s (bp)	Interaction Range r (bp)	χ2
1	20	3.04
2	10	1.65
2	20	1.72
2	50	1.74
3	3	2.3
3	4	2.8

Shown are just a few fits, obtained by varying s and r, from all those that are similar. The definition of similar is that the worst fit should be 0.5 times as likely as the best fit according to the AICc (see text for details).
