Query: Analytical Noise Bias Correction for Weak Lensing Shear Analysis with
  ERA   Highly precise weak lensing shear measurement is required for statistical
weak gravitational lensing analysis such as cosmic shear measurement to achieve
severe constraint on the cosmological parameters. For this purpose, the
accurate shape measurement of background galaxies is absolutely important in
which any systematic error in the measurement should be carefully corrected.
One of the main systematic error comes from photon noise which is Poisson noise
of flux from the atmosphere(noise bias). We investigate how the photon noise
makes a systematic error in shear measurement within the framework of ERA
method we developed in earlier papers and gives a practical correction method.
The method is tested by simulations with real galaxy images with various
conditions and it is confirmed that it can correct $80 \sim 90\%$ of the noise
bias except for galaxies with very low signal to noise ratio.
