Note:
    The default rate control policy for colour images employs visual (CSF)
    weighting factors.  To minimize MSE instead, specify `-no_weights'.

Generated 84 tile-part(s) for a total of 84 tile(s).
Code-stream bytes (excluding any file format) = 2,727,642 = 0.998197 bits/pel.
Layer bit-rates (possibly inexact if tiles are divided across tile-parts):
