Accelerometer data for experiment 08 at the SIO Pier

There are 4 data files (*.txyz) and 4 preliminary plots (*.jpg).
The data files each contain 4 columns: time(sec)   ax  ay  az
The accelerations are in meters/seconds_squared.  
ax and ay are the two horizontal components and az is the vertical component.
For the two experiments where the accelerometers were placed on the floating
surfboard, the ax component is roughly perpendicular to the axis of the
board while the ay channel is along the axis of the board.

The files CH25_2 and CH26_2 where collected nearly simultaneously

filename            start time       location
CH25_2.txyz         9:15:21 PDT      floating in bag
CH26_2.txyz         9:18:39          bag on longboard

CH25_3.txyz         9:57:16          floating in bag
CH26_3.txyz         9:57:51          bag on shortboard
(Note for this second experiment, the two accelerometers
were close together (< 2 m) starting at 10:01:00.)
