NNW

# Neural Network Weights for the SExtractor star/galaxy classifier (V1.3)

# inputs:	9 for profile parameters + 1 for seeing.

# outputs:	``Stellarity index'' (0.0 to 1.0)

# Seeing FWHM range: from 0.025 to 5.5'' (images must have 1.5 < FWHM < 5 pixels)

# Optimized for Moffat profiles with 2<= beta <= 4.
