ValueError: Parameter dannulus: value `0.xxx' is less than minimum `1.0'

[sameeresque]

I encounter this error,I couldn't locate where the setting for minimum value is done, could you comment?

[vterron]

What command are you using, and what was the full output?

I think I have also encountered this issue; when running with --individual-fwhm set, lemon no longer seems to apply the --min-sky option, and dannulus is too small.

Running the command

lemon photometry --overwrite --individual-fwhm --gaink=EGAIN --aperture=1.7 --annulus=2.5 --min-sky=3 mosaic_r.fits r0320*s.fits small_aperture_individual.LEMONdB

I get the following output:
