E) 1 # PSF fine sampling factor relative to data
F) mask.fits # Bad pixel mask (FITS image or ASCII coord list)
G) const.txt # File with parameter constraints (ASCII file)
H) 324 2656 602 2475 # Image region to fit (xmin xmax ymin ymax)

# INITIAL FITTING PARAMETERS
#
# For component type, the allowed functions are:
# sersic, expdisk, edgedisk, devauc, king, nuker, psf,
# gaussian, moffat, ferrer, and sky.
#
# Hidden parameters will only appear when they're specified:
# Bn (n=integer, Bending Modes).
# C0 (diskyness/boxyness),
# Fn (n=integer, Azimuthal Fourier Modes).
# R0-R10 (coordinate rotation, for creating spiral structures).
# To, Ti, T0-T10 (truncation function).
