Sažetak
The numerical kernel approach to difference imaging has been implemented and applied to gravitational microlensing events observed by the PLANET collaboration. A new algorithm is presented for determining the precise coordinates of the microlens in blended events, essential for accurate photometry of difference images. It is shown how the photometric reference flux can be obtained from measurements of the difference images combined with knowledge of the statistical flux uncertainties. An analysis of difference-imaging photometry of SAAO images of the moderate-magnifcation microlensing event OGLE 2008-BLG-229, reveals a systematic residual pattern in ISIS photometry that is not present in photometry from our new code. We draw attention to the fact that such residuals have the potential to be misinterpreted as planetary signals.
