The current bug is due to the incorrect calculation of band coordiantes.
This is due to the following variables in SIZ marker:

XRsizi:Horizontal separation of a sample of ith component with respect to
the reference grid. There is one
      occurrence of this parameter for each component.
YRsizi:Vertical separation of a sample of ith component with respect to the
reference grid. There is one
      occurrence of this parameter for each component.

XRsizi: 2, YRsizi: 1 for the file p1_01.j2k. I am not very sure how to use
these variables correctly to calculate band coordinate. I truly appreciate
your help.

Thanks
