[MSNoise] [EXTERNAL] CCF

[Thomas Lecocq]

Hi,

200s is long for stations 10 km apart, (200 km for surface waves at 
3.7km/s = >700 km wavelength


You can try to run

msnoise plot ccftime NET.STA1 NET.STA2 -r 0.1:2.0

where NET.STA1 and NET.STA2 are the network and station code of your 
stations (sorted alphabetically).

Cheers,

Thomas
