... The use of the parameters for the source and background extraction areas requires some care. ... In order to avoid these variations and to obtain a uniform combined light curve, it is better to use a fixed radius for the source extraction area for all the exposures in the ODF. ... Changing srcradius parameter one should also properly esablish the background extraction area setting bkginner and bkgouter parameters (see description of the parameters). ...
