Co-registration in snappy doesn't work

The problem is that the python value ‘0.05’ is a double-precision data type.
The Warp expects a single precision float value.
You can either remove the parameter rmsThreshold, because ‘0.05’ is the default, or you do the following:

Float = jpy.get_type('java.lang.Float')
parameters.put('rmsThreshold', Float(0.05))

I haven’t tried it, but I think this will work.
