Hi,
Additional question about the "deblend" script in starjava/bin/splat/
: is it possible to get more decimals on the parameter errors? For
example, I currently get this in the "report.log" output file:
Post-fit: GaussianFitter[flux = 7.295523848504501, (+/- 0.0), scale =
1.1952008680668813, (+/- 0.0), centre = -6.87900360112492, (+/- 0.0),
sigma = 2.435149604227493(+/- 0.0), FWHM = 5.734339100684084(+/- 0.0),
]
All I can infer from this is that the errors on each parameter are
smaller than 0.05 in the corresponding unit.
Cheers,
Matthijs
