# ISee! sample convolution kernel
#
# The kernel starts with a line containing x-size, y-size, 
# normalization factor and an offset (four numbers in one line).
# Then, the kernel data are listed line-by-line, space separated,
# empty or too short lines are not allowed.  Arbitrary comments 
# can be added after the kernel data.
#
# If you have problems creating new kernels or interpretating 
# existing sample kernels, have found an error, have questions
# or suggestions please do not hesitate to contact the ISee! developer
