[MSNoise] Issue in computing dtt

[Thomas Lecocq]

Hi,

It is difficult to know why you get those warnings (not errors!) when 
computing dtt, it's linked to the linear regressions. Do the resulting 
dtt look OK or are they full of NaN or INFs ? A reason could be that 
your dtt_* parameters are set to strict and there are not enough points 
for computing a linear regression. The only way to test this would be to 
edit the s06compute_dtt.py file in your install & add prints/debug 
information.

Regards,

Thomas
