Comparison - Here we compare the parameter fits using
DAOPHOT,
IRAF, and
SExtractor photometry. The first plot
is the chip-to-chip zeropoint relative to the reference chip, indicated by
the vertical dot-dashed line, and the second is the exposure-to-exposure
zeropoint relative to the first exposure. All y values are in magnitudes.
