READ-ME

These files contain the rectified video frames, as well as differenced and thresholded frames, from 14 February 2011, used to make Lambda(c) in Schwendeman et al. (2014).

Variables:
t - Matlab datenum of each frame (15 Hz)
x - Uniform gridded array of x values corresponding to the rectified videos (slightly different for each file).  Note that the ship was facing the opposite direction relative to the wave field for the earliest of these files (19:10 UTC).  So the dominant wave direction is in the -x direction rather than +x for this file only.
y - Uniform gridded array of y values (positive away from the ship) corresponding to the rectified videos (slightly different for each file)
rectFrames - rectified array of video data, ranging from 0 to 255.
diffFrames - array made by differencing subsequent frames.  Note that occasional frames are all zeros as part of a quality control procedure.
binFrames - binary array made by thresholding the array diffFrames.
