Abstract
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 for accurate photometry of difference images. It is shown how the photometric reference flux need not be measured directly from the reference image but can be obtained from measurements of the difference images combined with the knowledge of the statistical flux uncertainties. The improved performance of the new algorithm, relative to ISIS2, is demonstrated.

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 for accurate photometry of difference images. It is shown how the photometric reference flux need not be measured directly from the reference image but can be obtained from measurements of the difference images combined with the knowledge of the statistical flux uncertainties. The improved performance of the new algorithm, relative to ISIS2, is demonstrated.</div></front></TEI><affiliations><list><country><li>Afrique du Sud</li><li>Allemagne</li><li>Australie</li><li>Autriche</li><li>Chili</li><li>Croatie</li><li>Espagne</li><li>France</li><li>Nouvelle-Zélande</li><li>Royaume-Uni</li><li>États-Unis</li></country><region><li>Bade-Wurtemberg</li><li>District de Karlsruhe</li><li>Midi-Pyrénées</li><li>Occitanie (région administrative)</li><li>Vienne (Autriche)</li><li>Île-de-France</li></region><settlement><li>Heidelberg</li><li>Paris</li><li>Toulouse</li><li>Vienne (Autriche)</li></settlement></list><tree><country name="Nouvelle-Zélande"><noRegion><name sortKey="Albrow, M D" sort="Albrow, M D" uniqKey="Albrow M" first="M.
