Thanks Robin – yep – certainly don’t have the luxury of subtracting either image pre-SN like the surveys 😉 

I wonder if anyone has a suggestion on software to allow background modelling to allow me to reduce the data I have? AIJ doesn’t look to have this feature (it allows aperture photometry with background subtraction via an annulus, and (I suppose by setting the inner and outer background radii to the same value) PSF photometry without any background correction – possibly more accurate than the former, but then still prone to inaccuracies…
