Please let me know DR and FI of images without the pointing error.

RMS imaging error due to the pointing error is very small in 
my simulation but the deconvolution error due to limited (u,v)
coverage is also very small.  DR without the pointing error
is larger than 10,000.  In such case, the imaging error due to
the pointing error is comparable or larger than that due to 
the deconvolution error.
