Difference imaging photometry of blended gravitational microlensing events with a numerical kernel
Difference imaging photometry of blended gravitational microlensing events with a numerical kernel
The numerical kernel approach to difference imaging has been implemented and applied to gravitational microlensing events observed by the PLANET collaboration. The effect of an error in the source-star coordinates is explored and a new algorithm is presented for determining the precise coordinates of the microlens in blended events, essential …
